CBHD Community Sources: Forums, Press and Reviews

Why forums and trade press matter more than product pages

Manufacturer support sites for 2009 CBHD players are mostly dead. The densest surviving primary material sits in 2009-2011 forum threads and Chinese/Japanese trade press. AVSForum pages returned HTTP 402 when fetched directly in one research pass, so details below combine search snippets with cited URLs that still resolve when logged-in browsers or archives cooperate.

  • AACS Spec CBHD Prerecorded 0.90 (7 Oct 2008) PDF cited by ja.wikipedia.

Not yet searched or found empty

Baidu Tieba (CBHD吧, 蓝光吧, 新科吧), Chiphell, hifidiy, 影音极客, hifi.com.cn, AV前线, Zhihu, Douban groups, Doom9, videohelp, Myce/CDFreaks, AV Watch, Phile-web, Reddit beyond r/HDDVD, Youku, Xigua, Douyin and Weibo remain lightly touched or empty in the passes. Empty search results are not proof of absence-especially on Tieba and Douban.

For reconstruction work, prioritise: AVSForum master thread page 5 (TCL 维修手册 excerpts), LDDb HD-3700U owner posts, PConline/ZOL photo reviews, Memory-Tech press releases, and Wayback walks of shinco.com/chdia.org.cn. Those sources carry chip IDs, bundle lists, menu trees and pricing that product databases dropped years ago.

How to work the archive without the live web

Start with PConline’s five-page CBHD-9100 review and ZOL’s THBD-1008 hands-on pieces for UI photography and measured behaviour. Add pjtime’s 2009-2011 market series for price cuts, 3D launch notes and the June 2011 CMM statistic that blue-laser players were only 4.2 percent of 2010 disc-player unit sales. Tencent’s 5 July 2010 article pins TCL’s exit, the ~100-title plateau and the single 3D title. av269’s 15 January 2010 Guangzhou comparison supplies the 150-versus-1,800 title claim and the ~50,000 player estimate.

Japanese and English field reporting fills gaps Chinese marketing omitted: ITmedia’s Suning visit, Nikkei xTECH price economics, Diamond Online’s observation that software was online-only for one writer, Gigazine on TCL’s Toshiba internals, ASCII’s 2013 retrospective, and diit.cz on European arrival. CDRInfo’s cluster on CHDA structure, the HD DVD China logo and AACS mentions remains useful for standards chronology.

Forum triage order

  1. AVSForum master thread-especially page 5 service-manual excerpts.
  2. AVSForum User Reports-unboxing, CBHD-9000/CBHD-0002 photos, bundles.
  3. LDDb CBHD threads-HD-3700U quirks and trading.
  4. What Hi-Fi and DVD Talk-compatibility negatives.
  5. 2008 “China turns HDDVD into CBHD” thread-firmware debate context.

Manufacturer URLs to feed into Wayback include shinco.com news_id 312, 361 and 367, chdia.org.cn dynamic pages, Memory-Tech’s March/April 2009 announcements, and the AACS CBHD Pre-recorded 0.90 PDF cited by Japanese Wikipedia. Empty results on Tieba, Chiphell, Doom9 and Bilibili teardowns are unfinished searches, not closed cases. Budget time for logged-in AVSForum browsing because anonymous fetches returned HTTP 402 in one research pass.

Additional press anchors worth downloading before links rot further: cnBeta Warner-support and industrialisation interviews with Tian Yujing; big-bit pieces on Warner’s 100-title plan and the August 2009 sales-lead claim; Chinatimes launch planning; Sina’s December 2011 Shinco “cold market” post-mortem; What Hi-Fi’s CBHD-3D/HiFi coverage; DFC Intelligence’s 28 July 2008 royalty note; See You Next Wednesday’s May 2009 hack-hope blog; New Atlas and Tom’s Hardware launch notices. Each supplies a dated claim you can cross-check against CMM and Tencent later data.

Video remains thin: one YouTube clip is cited; Bilibili teardown searches misfired on unrelated Shinco VCD changers. Offering rewards in preservation Discord/QQ groups for phone video of menu trees and disc loads may outperform web search. When AVSForum returns payment walls, use search-engine caches and the Wayback Machine on thread URLs ending in page-4 and page-5.

pjtime’s Shinco brand news index still lists the 3 March 2010 CBHD-3800/HD-2100 article; av-china.com and Headphone Club covered HiFi/3D launch events in July and September 2010; CCCME summarised the 3D patent-pool working group. Launch reporting from a&s, Hualu and hxzg.net on 22 April 2009 still anchors the commercial start date. Cross-linking those URLs in a private archive before they disappear is itself preservation work. When citing forums, capture page numbers because AVSForum rewrites paths between forum and threads forms.

Building a personal source packet

Download and hash PConline’s CBHD-9100 review pages, ZOL’s THBD-1008 articles, the Sina Tech 3 April 2009 industrialisation piece on FSM patents, Memory-Tech’s two 2009 PDFs or HTML announcements, DFC Intelligence’s royalty note, and Tencent’s July 2010 market post-mortem. Store AVSForum thread IDs 1150473, 1149496, 1059383 and 1141114 with page snapshots. Keep LDDb topic 10789 and 11813. Add the AACS CBHD Pre-recorded 0.90 filename to the packet even if the PDF must be retrieved later from AACS LA or archives. That packet lets future researchers work offline when forums paywall or domains expire.

Pair each downloaded article with its access date and final URL redirect. Link rot is already visible across pjtime, big-bit and older Sina mobile mirrors.

Blog EVD Guides Open Questions
EVD Open Questions and Confirmed Facts

Separating the known from the missing

Enhanced Versatile Disc (EVD) research is uneven: some commercial and legal facts are multiply attested, while neighbouring questions that collectors naturally ask, exact model lists, named titles, container layout, codec of shipping discs, remain open. Separating the two is the point of this post. Confirmed items below are those the located English press, Chinese reference pages, E-World material and On2 SEC filings support. Unresolved items are framed as questions, not as guesses. Source conflicts that cannot yet be measured are kept as open disagreements rather than collapsed into a single settled story.

Confirmed facts

  1. Launch date and place. EVD was launched on 18 November 2003 at the Great Hall of the People with On2 VP5/VP6 announced and LSI Logic claiming the first HD EVD chips (EDN).
  2. On2 contract trail. The On2 contract terms, arbitration dismissal (10 March 2005) and unpaid 2006 settlement are documented in SEC filings.
  3. File-system standard entry. SJ/T 11299.2-2005 (file system) exists with 18 February 2005 dates, drafted by E-World and Shinco (standards platform).
  4. First player. The Shinco EVD-8700 was the first EVD player (1 January 2004, ¥1,998) and for a time the only one on sale (c114; Baidu).
  5. Named 2004 models. The Shinco EVD8830 and SVA EVD388 existed in 2004 (E-World material).
  6. December 2006 relaunch scale. The December 2006 relaunch showed about 54 players from about 20 makers at about ¥700 (AP).
  7. E-World software set. E-World had five software packages including an EVD disc authoring system and an OGT subtitle system (E-World material).

These seven points already constrain collecting. A deck without a period model story is not automatically “EVD” because a modern carton printed the three letters. The EVD-8700 / EVD8830 / EVD388 names are the documented early SKUs; the December 2006 “about 54 players” claim is a relaunch-era count, not a full serialised inventory. SJ/T 11299.2’s existence proves a file-system standard was filed; it does not put the full text of parts 1-4 into public hands. On2’s SEC trail proves contractual failure modes without proving which codec ultimately shipped on commercial discs.

What “confirmed” does not mean

Confirmed does not mean complete. The 18 November 2003 launch is attested; a title-level disc list from that day is not. VP5/VP6 was announced at launch; shipping-disc codec identity remains contested against later MPEG-2 MP@HL reporting. The EVD-8700’s first-player status is attested; the eleven launch players sometimes mentioned elsewhere and the fifty-four relaunch players are not inventoried by model here. E-World’s five software packages are named in secondary coverage; the binaries themselves are missing from public archives. SJ/T 11299.2’s catalogue dates are attested; whether the whole SJ/T 11299 family is still “current” or “withdrawn” is unresolved below.

Still unresolved

  • Which video codec shipping EVD discs actually use (MPEG-2 MP@HL-based vs VP6 vs other). Launch EDN coverage and later EE Times coverage disagree; keep both.
  • EVD directory and file names; container format.
  • Actual video bitrates of commercial discs.
  • ExAC bitrates, channel modes and whether it relates to Coding Technologies’ work.
  • The encryption scheme; whether any disc shipped with AACS.
  • Region coding, menus and navigation.
  • LSI Logic part numbers used in EVD players.
  • Model numbers of the 11 launch players and 54 relaunch players.
  • Any HD-EVD (2008) model.
  • A title-level disc list with 版号.
  • CNIPA patent numbers and the truth of the 2006 patent-pledge reports.
  • The “Hao Jie incident” of 2006.
  • Whether E-World ever paid the On2 settlement after 2009, and E-World’s corporate fate.
  • Current status of SJ/T 11299 (“current” vs “withdrawn”).

How to use the open list

Each unresolved item suggests a different next archive. Codec identity points at imaging a commercial disc and publishing ffprobe output after any decrypt path becomes available, and at re-reading EE Times 2006 beside EDN 2003 without forcing a premature synthesis. Directory and container work needs a published UDF file tree from a marked disc. ExAC questions need the SJ/T 11299.4 text or an E-World audio tool. Encryption and AACS questions need either the PC player binary (影海风雷 / E-World package) or a drive-authenticated read log. LSI Logic part numbers need board photographs from genuine players, not keyword-labelled portable DVD players from modern JD listings. Model inventories need 2004 and December 2006 retail photography and alliance press packs. HD-EVD needs 2008 product pages that name a chassis. Title and 版号 work needs Kongfz/Xianyu disc photography and national audio-video database queries. Patent-pledge claims need CNIPA record pulls. The Hao Jie incident needs the Huaqiang interview trail plus contemporary big-bit alliance reporting. On2 settlement and E-World fate need post-2009 corporate and SEC follow-up. SJ/T status needs a fresh standards-platform check against the existing 11299.2 catalogue entry.

Open disagreements to preserve

Two conflicts deserve explicit preservation as disagreements. First, video codec: November 2003 English launch coverage centres On2 VP5/VP6, while November 2006 EE Times relaunch coverage describes MPEG-2 MP@HL for commercial interest. Until measured streams from marked discs exist, both notes remain research status. Second, catalogue size: early counts of about 12-14 titles sit beside a Gome salesperson’s “hundreds,” E-World’s “more than 100,” and EE Times’ “about 100.” Those figures are kept side by side in the catalogue post; they reappear here only to warn that “confirmed launch” does not mean “confirmed filmography.”

A third soft disagreement sits behind player counts: “only EVD-8700 on sale” language in early reference pages, named EVD8830/EVD388 existence in 2004 E-World material, and AP’s December 2006 “about 54 players from about 20 makers.” Those are different moments, not a single contradictory census. Do not flatten them into one number.

A working research posture

The confirmed set is enough to begin serious collecting and dumping: know the launch date and On2/LSI Logic launch claims, know the On2 SEC contract trail, know that SJ/T 11299.2 exists on the standards platform, know the EVD-8700 first-player story and the EVD8830/EVD388 names, know the December 2006 relaunch scale language, and know that E-World shipped a professional software story including authoring and OGT tools. The unresolved set is enough to stop false catalogue and silicon inflation: no public container map, no measured bitrate table, no open ExAC decoder, no proven AACS-or-not answer, incomplete model lists, no HD-EVD SKU in hand, no title-level 版号 list, and unsettled patent-pledge and corporate-fate questions.

Modern shop keyword “EVD” still does not equal genuine 2004-2008 EVD with LSI Logic. Future posts in this series should promote an item from “unresolved” to “confirmed” only when a primary document, a measured disc, or a photographed SKU supports the move. Demoting a confirmed item should be equally explicit if a better primary source contradicts the press or FAQ summary used here. EVD history will not be completed by smoothing over gaps; it will be completed by filling them with the same discipline that already secured the seven facts above.

Blog Community Sources CVD Guides
CVD Community Sources: Forums, Press and Archives

Where CVD knowledge actually lives

China Video Disc (CVD) never acquired a single official English handbook that collectors could treat as canonical. What survives is a scattered archive: VideoHelp and AnandTech threads from the early 2000s, a handful of Doom9 and Ubuntu notes, Chinese newspaper pages from 1998 preserved on Guangming Daily and related sites, later Chinese retrospectives on dead VCD brands, and a thin set of Western technical guides headed by Jukka Aho’s Super Video CD overview. This post maps those communities and documents by what they contribute-not as a raw link dump, but as a research map of who argued what, when, and with which technical claim.

English-language forum memory

VideoHelp carried the densest English CVD conversation. SatStorm’s 2002 guide “CVD: What is it, how to test it & what to expect!” remains the practical entry point: history summary, a 352×576/480 encode recipe at 2,520 kbps, Region 1 player caveats, and C-Cube chip discussion. Adjacent threads compared CVD with DVD quality, debated whether “70% PAL / 30% NTSC” compatibility claims matched lived experience (including posters who said they had “never found” a working NTSC CVD player), and planned CVD-to-DVD migration while arguing over 44.1 versus 48 kHz audio on CD media and whether CD-R readability differed from format support on machines such as the Sony S560D.

Authoring threads preserved the hobbyist toolchain. Users shared Cinema Craft Encoder closed-GOP CBR recipes at 2,520 kbps and Kwag templates when VCD/SVCD/CVD encodes “none look great.” GNU/Linux writers documented jpeg2yuv / mpeg2enc / mplex stills and vcdxbuild menus. A 2024 VideoHelp thread still walks modern ffmpeg interlaced SVCD burning, showing that the authoring problem did not end with Nero-era Windows guides. Rip threads cover IsoBuster M2F2 extraction, vcdxrip, and VCDGear; subtitle threads contrast CVD versus OGT player support and recount an 1,800 kbps subtitle anecdote; burning threads compare Nero and VCDEasy compliance. Player-shopping threads name multi-format decks such as the Sampo DVE612 and note Apex dropping VCD. One laserdisc thread even records the recurring naming confusion between CD Video (CDV) and China Video Disc (CVD).

Outside VideoHelp, AnandTech threads called CVD the “best quality to size ratio” while warning it was “less compatible than SVCD,” sometimes citing an 80% compatibility anecdote, and debated picture quality against VCD with claims that CVD used “48 kHz audio” and TMPGEnc two-pass VBR. Those “48 kHz” remarks conflict with the 44.1 kHz Layer II practice documented for CD-based CVD and are kept as forum wording, not as a corrected specification. Doom9’s archive holds early CVD-style encode experiments framed as “SVCD with VCD resolution with MPEG-2.” Ubuntu Forums preserve a vcdxrip –nofiles tip for ripping to AVI workflows. The GNU help-vcdimager list (November 2001) discusses OGT subtitle IDs 0x70-0x73 and CVD subtitle compatibility-evidence that subtitle semantics were already a reverse-engineering problem, not a finished IEC story.

What forum consensus is worth

Forum numbers are observations, not standards. Compatibility percentages (70/30, 80%, “never found one”) must be kept as conflicting community claims. Encode recipes at 2,520 kbps document what hobbyists could burn, not what 1998 Chinese publishers necessarily pressed. Chip and player anecdotes are leads for hardware identification, not a substitute for decoder datasheets. The value of the threads is that they preserve test procedures, tool names, and disagreements that official marketing never recorded.

Chinese press archive, 1998

The primary documentary spine for CVD’s commercial year is Chinese newspaper coverage:

Date Paper Headline (short) Key content
21 Feb 1998 光明日报 Guangming Daily ’98影碟机市场… VCD service war; Beijing Blue Island stock
16 Jul 1998 文摘报 Wenzhai Bao CVD面世一月起风波 9 June launch; five makers; C-Cube; regulator warning; 65% share claim
22 Jul 1998 生活时报 Shenghuo Shibao 揭开CVD的面纱 (杨明贵) Jinzheng view; “first Chinese industry standard”; seven makers; prices
29 Jul 1998 生活时报 Shenghuo Shibao CVD是中国的“DVD”吗 (莫春) Market survey; 400 lines; 4 channels; Beijing meeting; Aido/SAST on sale
30 Sep 1998 光明日报 〈超级VCD系统技术规范〉11月初实行 SJ/T 11196 announced; effective 1 Nov
3 Nov 1998 光明日报 CVD与SVCD之争由标准转向市场 Seven-point CVD vs SVCD comparison; CVD 2000 project
16 Dec 1998 光明日报 PC业与VCD业之比较 CVD-SVCD war as marketing; joint 超级VCD promotion
20 Dec 1998 文摘报 Wenzhai Bao 超级VCD:自掘坟墓? (王健生) Compatibility war; interference codes; 280 vs 350 lines

Read as a sequence, the press arc moves from February’s ordinary VCD retail competition, through July’s CVD launch controversy and Jinzheng/Aido/SAST market talk, into September’s national Super VCD specification announcement, then November’s market-stage comparison and investment language, and finally December’s sceptical pieces that treat the CVD-SVCD fight as marketing while documenting interference codes and line-count claims (280 versus 350). Authors named in the digests include 杨明贵, 莫春 and 王健生-useful when tracing reprints. Launch-maker counts in July (five versus seven) and line-count rhetoric (400-line maker claims versus 280-line hostile framing) are themselves open disagreements elsewhere in this series; the press table is the citation spine, not a reconciled timeline.

Later Chinese retrospectives

After the format wars cooled, brand obituaries and technology essays kept returning to the VCD generation. Examples include Sina Tech’s 《六大品牌今安在?》 (10 February 2004), a People’s Daily digest 《与VCD一同谢幕的大佬们》 (1 August 2012), Zhihu and Sina Finance pieces on Aido (2018), chengww’s 《VCD–国产专利之痛》, and dwenzhao’s 《VCD的历史机遇与回响》. These are secondary for technical parameters but primary for what happened to launch brands and how Chinese writers later explained patent and market failure. Use them for company fate and political framing; prefer 1998 Guangming Daily / Wenzhai Bao / Shenghuo Shibao pages when parameters or dates conflict.

Western guides and documentation

Jukka Aho’s Super Video CD Overview (2001) is still the main English-language history covering CVD, SVCD and HQ-VCD, including Chaoji VCD requirements language. GNU VCDImager documentation (vcdimager.texi, vcd-info.texi) and the cvd-subtitles.pod note are the structural references for disc layout, tool options and CVD subtitle reverse-engineering. mjpegtools man pages and the MJPEG HOWTO document mpeg2enc/mplex profiles; ffmpeg documentation covers -target presets; DeVeDe / DeVeDeNG FAQs discuss CVD disc type and limitations. Windows-era guides on digitalFAQ and VideoHelp explain VCDEasy; xpt.sourceforge pages summarise VCD/SVCD/DVD differences and OGT selectable-subtitle workflows; Linux.com and O’Reilly’s Linux Multimedia Hacks describe VCDImager and cdrdao authoring paths.

Period and interpretive pieces round out the shelf: Russil Wvong’s Video CD FAQ for PC playback and Hong Kong distributors; noulakaz.net’s 2004 “China Video Disc” essay on CVD versus SVCD quality arguments; VideoLAN’s wiki page on CVD subtitles for VLC decoder behaviour; pctechguide’s SVCD digital-video article (an alternative history that must be cross-checked against Aho and Chinese press); and planetenumerique’s French “SVCD, la petite histoire,” which discusses CVD backers. Use these guides for tooling and vocabulary; prefer 1998 Chinese press and SEC C-Cube filings when the guides disagree about commercial history.

Gaps still empty

Several high-value Chinese channels have not yet been searched for CVD material: Xianyu (闲鱼), Taobao second-hand, Douban collector groups, Baidu Tieba (影碟机吧, VCD吧), and Bilibili teardowns. Trade magazines of 1998-电子报, 家用电器, 电子世界, 视听技术-are likely sources of model numbers and reviews but remain unread here. CNKI (中国知网) journal articles on 超级VCD/CVD have not been queried. Internet Archive captures of c-cube.com from 1998-2000, which may hold CVD decoder product pages, have not been mined. By contrast, eBay, Kongfz, JD and Suning were searched and returned no CVD-specific listings.

Community source work for CVD is therefore unfinished by design. The existing English forums preserve how Western hobbyists encoded and tested CVD-style discs; the 1998 Chinese newspapers preserve how the format was launched, regulated and competed with Super VCD; the tool manuals preserve how discs are structured today; and the empty Chinese second-hand and trade-press shelves are the next places a named player model or labelled disc is most likely to surface. Until those shelves are searched, catalogue and hardware posts in this series must keep inventing nothing: cite the thread, the newspaper, or the tool manual, and leave the gap visible.

Blog Buying & Sourcing CBHD Guides
Where to Buy CBHD Players and Discs

Current stockist status

No research pass found a reliable current commercial stockist of CBHD players or discs, or any live indexed listing. Searches covered eBay, Worthpoint, Kongfz, Xianyu, Taobao, Yahoo Auctions Japan, Mercari, Ruten, Carousell and Discogs (on the order of 32 queries in one pass). Chinese C2C platforms block most search indexing, so “not found” is not proof nothing is listed-Xianyu and Kongfz must be searched by hand in their apps. The Shinco CBHD-9100 is listed as discontinued in Chinese product databases. Manufacturing ended quietly around 2010-2011 without an official sunset announcement; sourcing means niche archival markets.

Historical retail geography

Mainland China: GOME and Suning (sales deals August 2009), Dazhong, plus online Joyo-Amazon, Dangdang and Taobao. Hong Kong: very limited imports. United Kingdom: GBAX imported the TCL THBD-1008 in October 2009 at £259.99 with 14 discs, and briefly imported small shipments of players and Warner discs into Europe. The GBAX product page, photos, manual, packaging and customer discussion may survive in web archives and are a preservation lead. Grey-market auction listings appeared occasionally during the format’s life.

Buying recommendations

  1. Search Xianyu and Kongfz by hand for 中国蓝光, CBHD, 新科 9100 and THBD-1008; set saved-search alerts. A buying proxy such as Superbuy can handle Xianyu purchases.
  2. Expect nothing on eBay or in Japan for finished CBHD goods.
  3. Collector route order: Chinese second-hand market → Japanese/Asian auction market → eBay/import sellers → collector forums → other Chinese used-goods platforms.
  4. Check LDDb forum trading threads and HD DVD preservation communities.
  5. Before buying repair donors, photograph the pickup label of a known CBHD unit.
  6. Ask sellers for photos of 说明书 and 保修卡-boxed units often still include printed manuals absent from the web.

Disambiguation tip: eBay “Shinco” hits are almost always standard DVD players. Confirm CBHD model numbers (CBHD-9100, CBHD-3800, HD-2100, HD-3700U, THBD-1008, THBD-1038) and look for bundled CBHD discs or the blue CBHD logo on the fascia before paying collector prices.

Why indexed search fails on Chinese C2C

Xianyu (goofish.com), Kongfz, Taobao and Zhuanzhuan often hide listings from external crawlers. Claude pass 2’s “nothing indexed” results across roughly thirty-two queries therefore mean “nothing visible to automated search,” not “zero units exist in drawers in Changzhou or Shanghai.” Manual app search with the Chinese strings listed above, saved alerts and buying proxies such as Superbuy remain the practical path. Japanese marketplaces returned articles rather than goods; Hong Kong saw only very limited imports historically; eBay currently shows ordinary Shinco DVD players that are not CBHD-capable.

Historical retail geography still guides where stock might surface: GOME, Suning and Dazhong stores once carried Shinco decks; Joyo-Amazon and Dangdang category pages from 2009 survive in Wayback and can yield title lists even when buy buttons are dead. GBAX’s UK THBD-1008 page at £259.99 with fourteen discs is a preservation lead for packaging photography and manuals if archive captures remain.

Price memory for negotiation

Knowing that a CBHD-9100 launched near ¥2,580 with fifteen discs, reviewed at ¥2,999, imported near $300, and later sold near ¥1,599 helps collectors judge modern asks. Discs that were ¥55 in 2009 and ¥28 online by 2010 should not be priced like rare Blu-ray steelbooks without provenance. Conversely, complete boxed players with manuals and unopened sampler discs are scarcer than bare decks and justify premiums-especially THBD-1008 units tied to the only documented overseas retail push.

Disambiguation remains critical: confirm model numbers CBHD-9100, CBHD-3800, HD-2100, HD-3700U, THBD-1008 or THBD-1038; look for the blue CBHD logo; ask for photos of disc bundles and 说明书. LDDb trading threads and HD DVD preservation groups occasionally move hardware when public marketplaces look empty. Photograph pickup labels on any working unit before buying “compatible” donors for repair.

Search-term hygiene: English “CBHD” collides with unrelated acronyms on Worthpoint; pair it with Shinco or TCL model numbers. Japanese queries such as 中国版HD DVD find articles more often than auctions. Traditional Chinese 中國藍光 helps on Ruten and Hong Kong boards even though historical imports were sparse. Always exclude generic “Shinco DVD” hits that lack CBHD badging.

Collector route reminder: Chinese second-hand apps first, then broader Asian auctions, then eBay/import sellers, then specialist forums. Expect long dry spells. When a unit appears, verify power-on, disc load, HDMI output and whether bundled discs are present-players without discs still play USB files on the 9100/3700U but lose catalogue value. For repair-only purchases, budget that pickup and firmware may not transfer from Toshiba donors without FSM-capable channel hardware.

Discogs currently lists China Record Corporation label pages without CBHD release entries-useful for publisher context, useless as a stockist. AliExpress and Amazon returned nothing in the passes. Naver, Coupang, Shopee SG/MY and Lazada were named in the brief but not searched in depth; they remain secondary checks after Xianyu and Kongfz. Grey-market auction appearances during 2009-2010 prove overseas trickle existed; they do not guarantee modern eBay depth. Patience and Chinese-language queries outperform English-only shopping.

What “nothing found” actually means

Across eBay regions the pass found ordinary Shinco DVD-860 and DVD-1000 class players, not CBHD machines-useful negative evidence that Western marketplaces currently mislabel or simply lack the format. Worthpoint’s unrelated CBHD acronym hits warn against keyword-only alerts. Japanese hard-off and Mercari emptiness matches the format’s China-primary distribution. Hong Kong Carousell emptiness matches ChatGPT pass 1’s “very limited imports” note. The positive lead list is short on purpose: Xianyu, Kongfz, LDDb trading threads, and occasional preservation-group offers. Set alerts, check weekly, and treat dry months as normal rather than proof the last player was destroyed.

When a listing appears, ask for power-on video, close-ups of the model badge, HDMI output to a TV, and photos of any bundled discs and printed manuals. For THBD-1008 specifically, ask whether the UK GBAX accessory set (PSU, AV cable, HDMI cable, fourteen movies) is complete. Incomplete bundles still matter; document missing discs so catalogue workers know which titles remain orphaned.

Historical online shops Joyo-Amazon and Dangdang matter less as buy buttons and more as Wayback category captures that still list title names, prices and cover art for catalogue building. Taobao sold discs under five dollars during the format era; modern Taobao searches must be manual inside the app. Keep a running shortlist of rejected false positives-generic Shinco DVD decks-so future searchers do not re-check the same eBay item numbers.

Save search alert screenshots so later researchers know which queries were already exhausted.

Blog Community Sources EVD Guides
EVD Community Sources: Forums, Press and Archives

Where EVD knowledge actually lives

Enhanced Versatile Disc (EVD) never acquired a single official English handbook that collectors could treat as canonical. What survives is a scattered archive: English trade-press pieces from 2003-2006, Chinese encyclopaedia and FAQ pages, contemporary Sina and PjTime reporting, a thin set of enthusiast forum threads, and SEC exhibits from On2. This post maps those communities and documents by what they contribute, not as a raw link dump, but as a research map of who argued what, when, and with which technical claim.

English press spine

Date Outlet Title / content
18 Nov 2003 EDN (Junko Yoshida) “China unveils its own video format”: VP5/VP6, LSI DoMiNo, McIntyre quotes
24 Nov 2003 EE Times / EDN “China’s EVD spec enters digital video fray”: codec options, AVS, “reincarnation of VCD”

Dec 2006 TechRadar “Chinese to challenge Blu-ray and HD DVD”
2003-2009 SEC EDGAR (On2) Contract exhibits and arbitration disclosures

Read as a sequence, the English arc moves from November 2003 launch coverage that foregrounded On2 VP5/VP6 and LSI Logic, through 2005 standard-and-lawsuit framing, into November-December 2006 relaunch coverage that named MPEG-2 MP@HL, roughly fifty-four players, and a roughly ¥700 price band. Those codec stories disagree across years and must stay side by side in technical posts; the press table is the citation spine, not a reconciled specification. On2’s SEC EDGAR trail is the primary Western document set for contract terms, arbitration dismissal and settlement language.

Chinese Wikipedia and Baidu Baike are secondary synthesising pages: useful for chronology and for names of halls, alliances and HD-EVD 2008 branding, but they must be checked against Sina, PjTime, EE Times and SEC when dates or codec claims conflict. The E-World FAQ on siga.org.cn is the closest thing to a vendor self-description of brands, prices and HD claims. PjTime’s 2007 explainer remains the densest single Chinese technical overview for software packages, named models (EVD388, EVD8830), publishers and ExAC talking points. c114’s encyclopaedia entry preserves the early “EVD-8700 only model” retail note and alliance/royalty language that hardware posts rely on.

News clusters matter as clusters. Sina’s March 2005 ¥3-5 disc promise, October 2005 “five measures,” September 2006 crisis reporting and the December 2006 relaunch burst are contemporary temperature readings, not later nostalgia. Nanfang Daily via PjTime in August 2007 (“EVD 的梦该醒了”) and Yicai’s Shinco restructuring piece document collapse and corporate aftermath. big-bit alliance reports and the Huaqiang Hao Jie interview preserve internal-camp friction language, including the “Hao Jie incident” still listed as unresolved elsewhere. gzhifi’s 2008 “true HD” piece is the source for Jindian’s fourteen-title first release claim. Douban note 876697066 is a collector-assembled clipping file for EVD/HDV/HVD reporting rather than a primary newspaper.

Later reprints

CSDN (2009) and 中国视听网 (2010) reprints of E-World-related material keep FAQ language circulating after original pages move. Prefer the earliest live or archived copy you can find when wording conflicts. ZOL’s 2009 “何为EVD” reprint and standards-battle features likewise often echo PjTime and FAQ text; use them for discovery, then walk citations back.

Forums

Forum Thread Note
非常发烧网 (hifi168) “EVD,大家听说过吗?有谁开始使用?” (19 Nov 2003) Contemporary enthusiast reaction

DVD Talk “Forward Versatile Disc (FVD)” FVD/Sigma press-release discussion
PjTime forum Linked from EVD articles Not searched

English enthusiast depth for EVD is thinner than for CVD or SVCD. hifi168’s 19 November 2003 thread catches Chinese enthusiast reaction within a day of the Great Hall launch. The gebi1 critical thread is logged as existing but unread because automated access was blocked. DVD Talk’s FVD thread is adjacent Taiwan-format discussion, not EVD primary evidence; it belongs on the related-formats shelf. PjTime’s own forum links from EVD articles remain unsearched and are a natural next pass for model and disc anecdotes.

Gaps still empty

Several high-value Chinese channels have not yet been searched for EVD material: Xianyu, Taobao, Baidu Tieba (影碟机吧, 高清播放机吧), Bilibili teardown videos, CNKI journal articles, CNIPA patents, archived evd.cn and jdglobal sites on the Internet Archive, AVSForum and CDFreaks threads. Those remain the places a named disc 版号, a board photograph of LSI Logic markings, or a surviving PC-player installer is most likely to surface.

Community source work for EVD is therefore unfinished by design. English trade press and On2 SEC filings preserve the Western launch and contract story; Chinese FAQ, encyclopaedia and Sina/PjTime reporting preserve retail, alliance and collapse language; forum threads preserve enthusiast suspicion and excitement; and the empty second-hand, Tieba, CNKI and Archive.org shelves are the next places catalogue and hardware posts should look before inventing titles or chip part numbers. Until those shelves are searched, cite the article, the FAQ or the SEC exhibit, and leave the gap visible.

Blog Buying & Sourcing CVD Guides
Where to Buy CVD Players and Discs

Current market reality

China Video Disc (CVD) hardware and discs from the 1998 launch window are not a clean marketplace category today. Searches on eBay, Kongfz (孔夫子旧书网), JD, Suning and ZOL have not turned up a listing that specifically advertises a 1998 CVD player or a disc marked “CVD.” What exists instead is a surrounding ecosystem: multi-format DVD players that claim Super VCD support, second-hand VCD film stock that may hide period 超级VCD discs, modern Chinese DVD/EVD decks that still print 超级VCD on the feature list, and spare C-Cube decoder chips for repair. Buying for CVD research therefore means hunting adjacent stock and testing it-not ordering a labelled “CVD starter kit.”

What is actually for sale

Multi-format DVD players (Western second-hand)

Generic DVD players marketed as “DVD / Super VCD / VCD / CD” are the common Western find, especially JVC XV-N series units. Recent listing examples include an XV-N510B around US$7.56, an XV-N33 around €17.97, and an XV-N212 around £18.99. Prices in the US$8-25 band are typical for that class of deck. These machines play Philips SVCD; CVD support is not stated on the carton language and must be tested before anyone buys in quantity. Treat “Super VCD compatible” as a necessary filter, not as proof of China Video Disc playback. Community compatibility claims for CVD on Western DVD players disagree sharply elsewhere in this series; a cheap XV-N is a test mule, not a guarantee.

Hong Kong VCD/DVD stock on eBay

eBay still carries Hong Kong VCD and DVD stock associated with distributors such as Mei Ah and Universe Laser. That stock occasionally includes Super VCD titles. It remains a useful search channel for period Asian optical media, but Mei Ah or Universe branding alone does not confirm CVD encoding. Discs must be inspected for markings, measured for video width, and tested across players. Russil Wvong’s Video CD FAQ already treated Hong Kong distributors as the Western hobbyist’s VCD pipeline in the late 1990s; the same pipeline is where Super VCD titles are most likely to hide today.

Kongfz out-of-print VCD film shops

Kongfz second-hand shops with large “VCD 电影 绝版” (out-of-print VCD film) categories are currently the most promising Chinese-language place to look for period 超级VCD discs. One documented shop lists 908 VCD film items in that category. Sellers may not distinguish CVD from Super VCD in the title field; photographs of the disc face, tray card and any 版号 string matter more than the shop’s search keyword. Ask whether the disc was a player giveaway (随机赠送) from 1998-1999-contemporary press described free bundled titles as a CVD marketing tactic-and image immediately after purchase.

Current Chinese DVD/EVD players

JD and Suning still list DVD/EVD-class players from Jinzheng, SAST, Malata and Amoi in roughly the ¥89-200 range. Feature lists typically include 超级VCD playback. CVD support is again not stated. These decks are candidates for modern SVCD testing and for everyday playback of ripped or re-authored discs; they are not substitutes for documented 1998 CVD launch hardware without chip and mechanism verification. Brand continuity (Jinzheng, SAST, Malata, Amoi) is historically suggestive but not evidence that a 2020s chassis still uses C-Cube CVD-era silicon.

C-Cube repair parts

Decoder chips for repair remain available from Taiwanese and Hong Kong component sellers. Examples include CL480T around US$9 on eBay and CL680-T128 stocked under US$1 in quantity on datasheet.hk listings. Chip availability does not recreate a 1998 player, but it does keep dead boards potentially recoverable and gives collectors a concrete parts vocabulary (CL480, CL484, CL680 and related C-Cube markings) when asking sellers what sits under the heat sink. Note that the discrete C-Cube CVD / Chaoji decoder part numbers and datasheets themselves remain unlocated; CL480/CL680 are the VideoCD-era family names still circulating in surplus, not proven CVD SKUs.

Historical retail channels (1998 and after)

Understanding where CVD sold when it was new helps explain where survivors may still hide:

Channel Period Notes
Shanghai department stores Jun-Nov 1998 CVD launch market; venue of November 1998 compatibility contests
Wuhan Jul 1998 CVD “sold quickly” (Shenghuo Shibao)
Beijing (e.g. Blue Island Building 蓝岛大厦) 1998 Aido and SAST CVD on sale; Blue Island stocked 60+ VCD models from 20+ brands
VCDGallery.com early 2000s Sold “original SVCD movies” online (cited via VideoHelp)
Five Star Laser (San Gabriel, CA); Blue Laser (Connecticut) late 1990s Western importers of Hong Kong VCDs

Shanghai is the political and marketing centre of the CVD story: launch events and later compatibility contests both sat in department-store retail culture. Wuhan’s “sold quickly” note shows that CVD hardware moved outside Shanghai within weeks of publicity. Beijing’s Blue Island Building (蓝岛大厦) appears in February 1998 Guangming Daily coverage as a dense VCD retail node-60-plus models from 20-plus brands-before becoming a place where Aido and SAST CVD machines were observed on sale later that year. Western importers such as Five Star Laser and Blue Laser, and later online shops such as VCDGallery.com, matter for diaspora and hobbyist SVCD/VCD collecting, not as proven CVD specialist shops.

Search terms that actually help

Language / focus Terms
Chinese (players) CVD影碟机; CVD机; 超级VCD影碟机; 超级VCD机 1998; 金正 CVD; 爱多 CVD; 先科 CVD; 万利达 超级VCD; 厦新 CVD; 步步高 超级VCD
Chinese (discs) CVD碟片; CVD光盘; 超级VCD碟片; SVCD 正版; 超级VCD 绝版; 随机赠送 CVD
English China Video Disc; CVD player; Chaoji VCD; Super VCD player Aido / SAST / Malata; C-Cube CVD
Parts C-Cube CL680; CL484; C-Cube Chaoji VCD decoder

Brand-linked Chinese queries (金正 / Jinzheng, 爱多 / Aido, 先科 / SAST, 万利达 / Malata, 厦新 / Amoi, 步步高 / BBK) outperform the bare English acronym “CVD,” which collides with unrelated uses. Disc queries that include 随机赠送 CVD (random/giveaway CVD) target the player-bundle distribution mode documented in 1998 press. English “Chaoji VCD” and “C-Cube CVD” catch Western chip and format discussions that never used the full China Video Disc expansion.

Platforms not yet searched in this research set include Xianyu (闲鱼), Taobao second-hand, Douban collector groups, Baidu Tieba boards such as 影碟机吧 and VCD吧, and Bilibili teardown videos. Those remain high-priority next channels precisely because Kongfz/eBay/JD/Suning already returned no CVD-labelled hits.

Buying recommendations

  1. For playing hobbyist CVD-style discs: any DVD player that already plays SVCD from CD-R is a candidate. Test playback carefully before buying multiples; carton “Super VCD” text is not enough.
  2. For period hardware: look for Chinese 1998-1999 超级VCD players from the CVD launch brands, and ask sellers for the decoder chip marking (C-Cube versus Shinco/ESS) and for a photograph of the mechanism (Philips versus Sony). Those two hardware axes are the period distinctions contemporary Chinese reporting used between CVD-camp and SVCD-camp machines.
  3. For period discs: search Kongfz and Xianyu for discs marked “CVD” (not only 超级VCD) from mid-1998, then image them immediately-labels, matrix codes, 版号, and tray cards-before the seller’s photos disappear.

How to budget a first purchase without fooling yourself

A realistic first shopping list for CVD research is therefore not a branded 1998 Jinzheng carton at a collector premium, because those listings have not appeared in the searched markets. It is a cheap SVCD-capable DVD player in the US$8-25 class, a Kongfz trawl through 绝版 VCD film lots with seller photo requests, optional modern Jinzheng/SAST/Malata/Amoi decks in the ¥89-200 band for daily SVCD work, and awareness of CL480/CL680 parts pricing if a board is already on the bench. Historical geography-Shanghai department stores, Wuhan quick sales, Beijing Blue Island stock, Western Hong Kong VCD importers-explains why survivors may surface as undifferentiated “old Chinese VCD player” lots rather than as museum-labelled CVD artefacts.

Until a seller photographs a disc face that literally says CVD, or a chassis with a documented C-Cube Chaoji VCD decoder and period branding, every purchase remains a compatibility experiment. That is the honest market condition for China Video Disc in the mid-2020s: adjacent formats are plentiful; labelled CVD objects are not yet on the searchable shelf. Budget for imaging and testing time, not only for the invoice price of the player or disc.

CBHD Disc Catalogue: Titles, Bundles and Prices

How large was the catalogue?

No complete catalogue, ISRC list or 版号 list was found. Contemporary claims mix plans, production counts and cumulative totals and should not be treated as a verified catalogue. Selected claims:

Date Claim Source type
Mar 2009 Warner plans 100 titles in 2009 CAV Warner MD 方东林 / big-bit
Mar 2009 CBC: 5 Chinese titles done, 20+ in production Memory-Tech
Apr 2009 25 titles ordered from Warner China and CRC Memory-Tech
Aug 2009 Warner + China Record to release 200 within the year 北京商报
21 Dec 2009 100 titles reached ja.wikipedia
Jan 2010 150 CBHD vs 1,800 BD titles; ~50,000 players sold av269 Guangzhou
Jan 2010 Hongyi: 10 in run, 35 in production, 120 planned for 2010 Press
2010 CAV Warner ~80 released, 200+ planned cnBeta
Mid-2010 ~100 titles; one 3D title Tencent

Assessment: 100+ titles is plausible and contemporaneously claimed; 1,000 released titles is not established; “only a few hundred titles ever existed” is also not established. Build the catalogue title by title. By mid-2009 only Warner’s library and Chinese titles were officially available; other majors had not yet committed catalogues.

Confirmed and reported titles

Record each disc as commercial standalone, bundle-only, demonstration or promotional. Technical profiles such as “1080p AVS, DRA 5.1” appear in one secondary pass and are not verified by MediaInfo across the set; early 2009 discs likely used VC-1/AVC.

  • CAV Warner launch / retail: Harry Potter and the Philosopher’s/Sorcerer’s Stone; Chamber of Secrets; further Potter entries advertised through Half-Blood Prince; Blood Diamond (血钻); The Golden Compass; Speed Racer; The Aviator (飞行者); Poseidon (海神号); The Polar Express (极地特快); The Invasion (致命入侵); Batman Begins; Superman Returns; Charlie and the Chocolate Factory; The Ant Bully; Scooby-Doo (sampler).
  • Bundle / multi-channel evidence: The Island (逃出克隆岛); The Warlords (投名状); Flood (水啸雾都).
  • Taobao / street mentions: Transporter 3; Lord of War (under $5).
  • Notable non-HD-DVD title: Slumdog Millionaire (ITmedia, Oct 2009)-example of a CBHD title never released on HD DVD.
  • Chinese specials: Song Zuying Jasmine (茉莉花) concert; Monkey King sample; 60th National Day military parade; National Geographic 5-disc set (eetrend, Apr 2010); one unnamed CBHD-3D title (Tencent, Jul 2010); Guangzhou Asian Games ceremonies planned in 3D; China Record music documentaries as CBHD-HiFi collector editions (24-bit/192 kHz LPCM).

CBHD was not simply a reissue service for dead HD DVD titles. No pass identified specific HD DVD-only reissues beyond Warner catalogue titles that had also existed on HD DVD.

Player bundles

Sampler bundles were non-standardised by batch, factory and model-5-disc or 10-disc sets in keep cases or paper/multi-disc sleeves.

Bundle Size Known contents
Shinco CBHD-9100 launch 15 (not sold separately) The Warlords, The Island, Flood + 12 others

ja.wikipedia note 16 –
Suning Shanghai Apr 2010 10 –
Factory sampler sets 5 or 10 Harry Potter 1-2, Polar Express, Ant Bully, Scooby-Doo among reported

Disc prices

  • Launch: ¥50-70 ($7.25-$10.15).
  • Nikkei xTECH (4 Aug 2009): ¥55 CBHD vs ¥175 Blu-ray vs ¥60 pirated BD.
  • Later: ¥25-30; ¥28 online by 2010; ¥28-55 in Guangzhou, Jan 2010.
  • Taobao: Transporter 3 and Lord of War under $5.

Studios and publishers

Documented supporters: Warner Bros. (CAV Warner), Universal, National Geographic, Paramount, Celestial Pictures, BBC/Discovery, China Record Corporation, China Film Audio-Visual Press, Hongyi and other domestic studios. Universal and National Geographic announced support at the September 2009 Guangzhou conference. Eetrend (April 2010) lists Warner, Universal, Paramount, Fox and National Geographic content. Support announcements do not equal verified release catalogues-separate the two in any database. November 2009 reporting claimed every CBHD disc so far was issued by 中录.

Building the catalogue responsibly means photographing keep-cases, recording 版号 when printed, noting bundle vs retail SKUs, and refusing to inflate totals from alliance “1,000 titles in 2010” targets that never materialised.

How to build the database without inventing titles

Every catalogue row should carry evidence tags: launch announcement, retail keep-case photograph, bundle-only, sampler sleeve, Taobao listing screenshot, or press mention only. Warner’s March 2009 announcement named Harry Potter, The Golden Compass, Speed Racer and Blood Diamond among launch titles at ¥50-70. Bundle photography and AVSForum unboxings extend the list with The Aviator, Poseidon, The Polar Express, The Invasion, The Island, Flood and The Warlords. Taobao-era mentions add Transporter 3 and Lord of War at under five dollars. ITmedia’s October 2009 field report uses Slumdog Millionaire as an example of a CBHD title that never appeared on HD DVD-proof the format was not solely a dump of dead Western HD DVD SKUs.

Technical columns for “1080p AVS, DRA 5.1, dual-layer 30 GB” appear in one secondary pass for several Warner keep-cases and should be marked unverified until MediaInfo or bitstream logs exist. Claude pass 1 notes early 2009 discs likely used VC-1 or AVC because AVS encoders were missing at China Record. Sampler packs may mix single-layer 15 GB children’s titles (The Ant Bully, Scooby-Doo in Gemini’s notes) with dual-layer features.

Publishers versus announcements

CAV Warner and 中录 dominate verified early output; fx361 claimed in November 2009 that every CBHD disc so far was issued by 中录. Universal, National Geographic, Paramount, Celestial Pictures and BBC/Discovery announced support around the September 2009 Guangzhou conference, yet substantial released catalogues for those brands are not established. Hongyi announced ten titles in a production run, thirty-five in production and 120 planned for 2010-plans, not a finished filmography. China Film Audio-Visual Press and China Record music documentaries (including CBHD-HiFi editions) belong in separate product-type fields from feature films.

Bundle heterogeneity matters for collectors: Shinco launch 15-disc packs, UK GBAX 14-disc THBD-1008 packs, October 2009 25-disc import packs, Suning 10-disc promotions and factory 5/10-disc samplers are different SKUs. Price history from ¥50-70 to ¥28 online and street undercutting by BD-9 piracy frames why catalogue growth stalled even when alliance slides still promised 1,000 titles.

National Geographic’s five-disc set (eetrend, April 2010), Song Zuying’s Jasmine concert, the Monkey King sample, the 60th National Day military parade disc and the unnamed CBHD-3D title show that non-theatrical product types matter. CBHD-HiFi music documentaries from China Record using 24-bit/192 kHz LPCM belong in an audio-product table, not mixed blindly with feature SKUs. Planned Guangzhou Asian Games 3D ceremonies may never have shipped; keep them in a “planned” status field.

Cumulative claims to reject as verified totals: 1,000 titles released in 2010; “only a few hundred ever existed” as a hard ceiling; Warner’s 100-title plan as proof of 100 finished SKUs. Accept as working estimates: about 100 titles by late 2009/mid-2010; about 150 in one January 2010 Guangzhou report; CAV Warner near 80 released with more planned per cnBeta. Build upward from photographed and cited titles instead of downward from alliance slides.

Potter entries through Half-Blood Prince appear as advertised rather than equally well evidenced; catalogue rows should distinguish launch announcement, advertised, and bundle photographed. Batman Begins, Superman Returns and Charlie and the Chocolate Factory sit in Chinese distribution reports for 2009. Eight or ten unnamed Chinese titles in TCL bundles remain anonymous until spines are photographed. Twelve unnamed titles in the Shinco fifteen-disc launch pack similarly await identification. Anonymous bundle slots are catalogue debt, not proof those slots were blank.

Evidence discipline for collectors

Photograph both keep-case spines and disc labels; Chinese 版号 strings often appear only on packaging. Note whether a disc came from a player carton or a retail shelf. Record layer count if printed. Separate demonstration and promotional discs from commercial features. When Gemini lists AVS and DRA 5.1 for a title, copy that claim into a “reported profile” field rather than a “verified bitstream” field. When Claude notes early VC-1/AVC likelihood, keep a “codec uncertainty” flag on all pre-September 2009 release dates. Catalogue work is cumulative: each photographed spine reduces reliance on alliance press maths.

Blog Buying & Sourcing EVD Guides
Where to Buy EVD Players and Discs

Current market reality

No confirmed listing of a genuine Enhanced Versatile Disc (EVD) player or a commercial EVD disc was found on JD, Suning, eBay, Kongfz or Chinese Wikipedia-linked shops in the research passes behind this series. Current searches for “EVD” on JD and Suning return DVD players, portable DVD players and Blu-ray players. That keyword collision is the central buying hazard: modern EVD retail language is not the same thing as a genuine 2004-2008 EVD deck with LSI Logic decode.

What current platforms actually show

Platform What to expect Source
JD (京东) “EVD” used as keyword on DVD/Blu-ray players; filter by brand and year JD
Suning (苏宁易购) Same pattern; e.g. Jinzheng portable “evd” DVD players at ¥369-519 Suning
Kongfz (孔夫子旧书网) Second-hand shops with large out-of-print disc categories; best chance for period EVD discs Kongfz VCD/disc category practice
Xianyu (闲鱼) Second-hand players and discs; not searched in this set –
Taobao second-hand Not searched –
eBay Chinese-region DVD players occasionally listed; no EVD found –

Kongfz remains the most promising Chinese-language place to look for period discs because its second-hand shops already organise large out-of-print film categories. Sellers may still misuse “EVD” as a vague high-definition adjective. Photographs of the disc face, EVD logo, publisher mark and 版号 matter more than the search keyword. Xianyu and Taobao second-hand were not searched here and remain high-priority next channels precisely because JD/Suning/eBay already returned no confirmed genuine objects.

Jinzheng portable players advertised with an “evd” keyword in the ¥369-519 Suning band are useful as negative examples. They show how the three letters still sell in Chinese retail search, and they show how far that marketing language has drifted from 2004-2008 living-room EVD with LSI Logic silicon and component HD outputs. Treat them as ordinary DVD/portable DVD hardware unless a seller can prove otherwise with model numbers from the period list below.

Historical retail channels (2004-2007)

Channel Role Source
Gome (国美) Launch channel; chair of 2006 alliance; 30 EVD stores planned pass 1; Baidu
Dazhong (大中电器) First EVD HD experience hall, June 2004 Baidu
Suning (苏宁) Listed by E-World as a retailer; later refused EVD as “fake HD” E-World FAQ; pass 1
Yongle (永乐) Listed by E-World E-World FAQ
Manufacturer counters Shinco, Amoi department-store counters E-World FAQ
搜E网 Planned online EVD store (2006) pass 1
800 disc outlets Planned (2006) pass 1

Historical geography explains where survivors may still hide. Gome was both a launch channel and, later, chair of the 2006 alliance that planned thirty EVD stores. Dazhong’s June 2004 HD experience hall is an early public demonstration node. E-World’s own FAQ listed Suning and Yongle among retailers even as other reporting notes Suning later refusing EVD as “fake HD.” That Suning contradiction is itself a buying lesson: a chain name that appears in vendor FAQ copy is not automatically a friendly modern stockist for genuine discs. Manufacturer counters for Shinco and Amoi matter because period hardware often moved through brand floors rather than through a single EVD specialist chain. Planned 2006 outlets (搜E网 online; eight hundred disc outlets) are capacity pledges, not proof that those nodes still hold stock today.

When a second-hand seller claims a machine “came from Gome” or “was from a department-store counter,” ask for carton photos, warranty cards and model stickers rather than accepting the story alone. Launch-channel provenance is historically plausible for Shinco and alliance-era decks; it is also easy to invent in a listing title. The same caution applies to discs said to be “Jindian Global from 今典” without a readable publisher mark in the photograph.

Search terms that actually help

Language / focus Terms
Chinese, players 新科 EVD-8700; 新科 EVD8830; 新科 EVD-327; 上广电 EVD388; EVD影碟机 2005; EVD高清碟机 老; 真高清 EVD 碟机; EVD 播放机 LSI
Chinese, discs EVD碟片; EVD光盘 正版; 今典环球 EVD; 中凯 EVD; 中影 EVD; EVD 高清影碟; HD-EVD 碟片
English Enhanced Versatile Disc; EVD player Shinco; EVD disc Jindian; HD-EVD

Model-linked Chinese queries outperform the bare acronym. Shinco EVD-8700, EVD8830 and EVD-327, and SVA (上广电) EVD388, are period SKUs named in E-World and reference material. Adding LSI to player searches targets the decode silicon story rather than keyword-stuffed portable DVD players. Disc queries that name Jindian Global, Zhongkai or China Film outperform generic “高清影碟” alone.

Filter out listings after 2009 and anything describing a “DVD播放机” with “EVD” merely appended. Ask sellers for a photo of the disc tray area showing an EVD logo and of the rear panel showing component HD outputs. Those two photographs separate living-room HD EVD hardware from ordinary DVD chassis that borrowed the three letters for search ranking.

Buying recommendations

  1. Buy genuine players only with the model number visible (EVD-8700, EVD8830, EVD-327, EVD388) and ideally with a commercial EVD disc included.
  2. Buy discs only with a visible Jindian Global, Zhongkai or other listed publisher mark and an EVD logo.
  3. Image discs immediately on receipt using the preservation workflow in this series.

A realistic first shopping list is therefore not a JD portable “evd” DVD player in the ¥369-519 band. Those machines document how the keyword is abused, not how 2004-2008 LSI Logic EVD worked. Budget instead for seller photo requests, Kongfz trawls through out-of-print disc lots, and immediate imaging time if a marked disc appears. Historical channels (Gome, Dazhong, Yongle, Shinco/Amoi counters) explain why survivors may surface as undifferentiated “old Chinese HD disc player” lots rather than as museum-labelled EVD artefacts.

If a candidate player arrives, verify the rear panel for component HD outputs, open or photograph the decode board for LSI Logic markings when safe, and test with an ordinary DVD first so you know the laser path works before you risk a scarce EVD title. If a candidate disc arrives, refuse to play it heavily before imaging: the preservation post’s ISO, hash, file-tree and dual-player test package is the purchase receipt that later research can reuse. Bundled player-plus-disc lots are especially valuable when both objects can be authenticated together, because period marketing often joined hardware sales to content supply.

Until a seller photographs a disc face with an EVD logo and publisher mark, or a chassis with a documented period model number and component HD outputs, every purchase remains an authenticity experiment. That is the honest market condition for EVD in the mid-2020s: the three-letter keyword is plentiful; confirmed 2004-2008 objects are not yet on the searchable shelf.

Blog CVD Disc Catalogue Guides
CVD Disc Catalogue: Titles and Bundles

What the catalogue evidence actually shows

China Video Disc (CVD) research has not yet produced a title-by-title catalogue. No ISRC list, no 版号 (publication number) register, and no named commercial CVD feature have been identified. The evidence that does survive is aggregate: contemporary Chinese press claims about how many discs were being bundled, how many publishers were “gradually” feeding the market, and how disc cost compared with Video CD. Building a CVD filmography therefore starts from those aggregate claims, from the content types the 1998 sources describe, and from a recording template that collectors can apply the moment a real disc appears-rather than from a finished list of spines.

That absence is itself historically meaningful. CVD launched into a saturated VCD retail culture in mid-1998, with player makers competing to give discs away and regulators and industry bodies already steering the market toward the Super VCD (超级VCD) national specification. Disc production was discussed as a supply problem for hardware sales, not as a curated prestige catalogue. Press language about “thousands of discs” and “several hundred titles” must be read with that commercial context in mind.

Catalogue-size claims, mid-to-late 1998

The dated claims cluster tightly between July and December 1998:

Date Claim Source
Jul 1998 Jinzheng will give away CVD discs with its players Shenghuo Shibao, 22 Jul 1998
Jul 1998 CVD discs “not yet widespread” Shenghuo Shibao, 29 Jul 1998
Nov 1998 Several hundred CVD titles bundled free by a dozen or so player makers Guangming Daily, 3 Nov 1998
Nov 1998 Thousands of discs from nearly 20 audio-video publishers “gradually flowing into the market” same
Nov 1998 “CVD 2000 project” to invest ¥200 million in disc production same
Nov 1998 SVCD makers to release nearly 100 titles by year end same
1998-1999 Super VCD discs produced with player-maker backing; some carried interference codes Wenzhai Bao, 20 Dec 1998

Two reading rules follow. First, “thousands of discs” most likely means disc units or SKUs across all publishers, not thousands of distinct programme titles; the Guangming Daily article does not say which. Second, the November 1998 “several hundred CVD titles” figure is tied to free bundling by player makers, not to a verified retail filmography. Treat “nearly 100” Super VCD titles by year-end as a parallel SVCD-camp claim, not as proof that CVD and SVCD catalogues were the same size or the same titles.

The July 1998 Shenghuo Shibao pairing is especially useful for chronology. Jinzheng’s giveaway plan shows that hardware vendors treated discs as launch incentives before a deep retail catalogue existed. The same month’s survey language that CVD discs were “not yet widespread” confirms that early abundance claims, if any, were aspirational. By November the story had shifted from scarcity to industrial scale-publishers, investment projects, and competitive title counts-while still refusing to name individual programmes.

The CVD 2000 project as a catalogue risk

Guangming Daily’s mention of a “CVD 2000 project” intending ¥200 million of disc-production investment belongs in the catalogue file as a planned capacity claim, not as evidence that those discs shipped. Whether the project actually produced commercial CVD titles remains an open question elsewhere in this series. Catalogue rows must not invent titles from investment headlines. The correct status for CVD 2000 output is “announced investment; production unverified.”

Likely content types, not title lists

The 1998 sources and Baidu Baike’s Super VCD article indicate the programme mix that Chinese audio-video publishers were already set up to supply: feature films, karaoke (the four-channel audio pitch was aimed at karaoke use), MTV music videos, scenic films, and science and education titles. Baidu’s SVCD entry notes that such material could “easily be converted to Super VCD format for publication,” because Super VCD was an open production specification whose disc cost matched VCD apart from content royalties. That conversion language explains why contemporary writers often talked about content families rather than about unique CVD franchises.

For collectors, content-type fields therefore matter more than premature title guesswork. A karaoke CVD and a feature CVD are different preservation objects even if both are unmarked “several hundred titles” in a 1998 newspaper sentence. Scenic and science-education discs may survive in school and tourism stock rather than in film-collector shops. None of those inferences invents a named title; they only map the categories the sources themselves describe.

Publishers and pressing plants: named gaps

The “nearly 20 audio-video publishers” (音像出版社) of November 1998 remain unnamed in the located press. No pressing plant, matrix code family, or 版号 series for CVD has been identified. The only named production tool in the research set is Beijing Galaxy Computer’s domestic Super VCD authoring system-useful for understanding how open Super VCD production was supposed to work, but not a CVD title credit.

Hong Kong publishers Mei Ah Entertainment and Universe Laser were major VCD and DVD distributors in the period and appear repeatedly in Western Video CD FAQs. No CVD or SVCD release by either firm has been confirmed. That negative finding is important: Western eBay “Hong Kong VCD/DVD” lots are not automatically CVD finds, and Mei Ah / Universe branding alone does not prove Super VCD or China Video Disc encoding. Period Hong Kong stock remains a search channel, not a verified CVD publisher list.

Bundles versus retail SKUs

Jinzheng’s July 1998 giveaway plan and the November claim of several hundred titles “bundled free by a dozen or so player makers” establish player-bundle discs as a primary CVD distribution mode. Catalogue discipline therefore requires separate product classes:

  • Commercial standalone – sold as a disc SKU without a player carton’s obligation.
  • Player-bundle disc – supplied with a CVD or 超级VCD deck; may never have had a shelf price of its own.
  • Demonstration disc – store or factory demo material.
  • Promotional disc – marketing giveaways beyond the player carton.

Wenzhai Bao’s late-1998 note that Super VCD discs were produced with player-maker backing, and that some carried interference codes, further warns that “disc found in a 1998 carton” is not the same evidence class as “disc bought as a named title.” Interference-coded discs may have been compatibility weapons in the CVD-SVCD market fight rather than ordinary retail programmes. Record them, but do not fold them blindly into a commercial feature count.

Prices: VCD parity as the business model

Item Price claim Source
CVD disc (1998) About the same as a VCD disc Jinzheng article, Shenghuo Shibao, 22 Jul 1998
Super VCD disc (1998) Cost equal to VCD; retail slightly higher due to licensed content Baidu Baike SVCD

Price parity with VCD was part of CVD’s pitch against DVD’s higher cost structure. It also helps explain why publishers and player makers could talk about flooding the market with bundled titles: incremental disc cost was familiar CD-family economics. Super VCD’s “cost equal to VCD, retail slightly higher for licensed content” claim is the open-standard counterpart. Neither figure yields a title list, but both constrain what a future photographed CVD package should look like economically-mass-market, not boutique.

Recording template for every new find

Until named titles appear, the useful catalogue is a protocol. Each disc found should be recorded with:

  • Title in Chinese and English (even if English is a provisional romanisation).
  • Publisher name as printed.
  • 版号 and/or ISRC if present.
  • Disc marking: CVD, 超级VCD, SVCD, or mixed/ambiguous labels.
  • Number of discs in the set.
  • Video width from ffprobe (352 versus 480 is the technical discriminator discussed elsewhere in this series).
  • Subtitle stream type.
  • Audio track count and channel layout.
  • Player bundle association, if any.
  • Pressing plant marks and matrix codes.
  • Date evidence (packaging, receipt, publisher colophon, bundle carton).
  • Whether the disc plays on multiple player brands.

Then classify the object as commercial standalone, player-bundle, demonstration, or promotional. That classification prevents bundle giveaways from being double-counted as retail catalogue growth when later researchers finally acquire numbers.

How to read “several hundred” without inventing spines

A responsible CVD catalogue page must refuse two temptations. The first is to invent plausible 1998 Chinese film titles and attribute them to CVD because “everyone was releasing VCD then.” The second is to treat Super VCD and CVD as interchangeable SKUs whenever a Kongfz shop labels a lot 超级VCD. Disc marking, video width, subtitle format, and playback behaviour across brands are the fields that will eventually sort the pile.

What can be stated now is limited and still valuable: July 1998 discs were not yet widespread while Jinzheng planned giveaways; by November a dozen-odd player makers were said to be bundling several hundred CVD titles and nearly twenty publishers were feeding thousands of discs into the market; an SVCD-camp claim of nearly one hundred titles by year-end sat beside a ¥200 million CVD 2000 ambition; disc cost was pitched at VCD parity; content families were film, karaoke, MTV, scenic, and education; publishers and plants remain anonymous; Mei Ah and Universe are unconfirmed for CVD/SVCD; and no individual commercial title name has yet been recovered. Until a labelled disc is photographed and measured, the CVD catalogue is a set of claims about volume, distribution mode, and programme type-not a filmography.

Blog CBHD Guides Home Authoring
Home Authoring and CBHD Reconstruction

Positions across the research passes

Home authoring is the most contested chapter in the CBHD record. Passes disagree on whether a disc burned on ordinary DVD media can play in a CBHD player. Summary:

Pass Position
ChatGPT pass 1 No end user could author CBHD with typical DVD tools; ordinary PC DVD/Blu-ray burners cannot produce CBHD discs.
Claude pass 1/2 No documented home method. Theoretical route blocked by FSM: no consumer burner writes FSM. Whether players read DVD-R with a CBHD folder structure is untested.
ChatGPT pass 2 Separates three projects (CBHD-like disc, playable CBHD image, physical CBHD); physical CBHD needs FSM mastering.
Gemini Practical pipeline: AVS via libxavs, LPCM/AC3, MPEG-2 TS mux, CBHD_TS tree, UDF 2.50 ISO burned with ImgBurn to DVD+R DL, claimed playable on Shinco HD-3700U or TCL THBD-1008.

Gemini presents the pipeline as working, citing LDDb threads, What Hi-Fi, Wikipedia and general burning guides. Claude and ChatGPT passes found no documented case of a burned disc playing in a CBHD player and argue DVD burners write EFM+, not 4-6 FSM. Directory models also diverge (CBHD_TS vs EVOB/HD DVD Book 3).

Gemini pipeline (as stated)

Step 1 – encode strict AVS (GB/T 20090.2) elementary video with FFmpeg linked to libxavs, example constraints: ~15 Mbps average, maxrate 18M, closed GOP N=12 for 23.976 fps, Jizhun Base Profile Level 6.1, yuv420p. Commercial averages 12-18 Mbps sit under the CHDA 28 Mbps video ceiling.

Step 2 – audio: DRA via the Tsinghua thesis encoder if available; otherwise 16/24-bit LPCM or stereo/5.1 AC3/DTS for legacy decoder paths.

Step 3 – mux to MPEG-2 Transport Stream and lay out:

VOLUME_ROOT/
├── CBHD_TS/
│   ├── CBHD_TS.IFO
│   ├── CBHD_TS.BUP
│   ├── ITEM_001.AVS
│   ├── ITEM_001.MAP
│   └── MENU_01.AVS
└── ADV_OBJ/
    └── CETC_NAV.DAT

Primary folder CBHD_TS (or HVDVD_TS on early CH-DVD transition discs) at volume root. CBHD_TS.IFO holds stream map, sector pointers, resolution and audio assignments; without it, players such as the HD-3700U may fall back to browsing an unparsed file structure.

Step 4 – build UDF 2.50 (or 2.01 with Unicode) ISO, uppercase ASCII volume label, burn at low speed to dual-layer DVD+R. Gemini states the pickup then reads the 0.6 mm layer, recognises UDF, finds CBHD_TS and plays through onboard AVS decode. HD DVD-R blanks are also listed among usable media in that account.

Directory model comparison

Model Top-level Containers
Gemini CBHD_TS/, ADV_OBJ/ MPEG-2 TS/PS; .AVS, .MAP, .IFO/.BUP, CETC_NAV.DAT
HD DVD-derived HVDVD_TS/, ADV_OBJ/ EVOB / EVO (MPEG-PS)
Unknown Requires real disc image –

Claude theoretical route (untested)

Encode with libxavs or AVC; audio AC-3 or thesis DRA; mux to EVO/program stream in HD DVD Standard Content style; build UDF 2.5 image. Blocker: pressed CBHD uses FSM and no consumer burner writes FSM. Whether players accept DVD-R media carrying a CBHD folder structure-analogous to HD DVD’s “3× DVD” method-is untested. That route would also need DKAA or an unencrypted mode players accept. The only documented realistic home-content route on original hardware remains USB file playback on the CBHD-9100 (1080p files, TS/MP4, external subtitles), with HD-3700U adding AVI and network shares.

Three projects that must not be conflated

Project Goal Difficulty
A. CBHD-like video disc UDF + compatible streams + simple navigation Approachable once logical format is recovered
B. Playable CBHD image Structure accepted by a real CBHD player Hard (CETC + Book 2/3 details)
C. Physical CBHD Data on CBHD physical media 405 nm, NA 0.65, FSM, channel coding, replication

VCD became accessible because its physical layer was standard CD. CBHD kept UDF, but its physical layer is not ordinary DVD burning.

Recordable CBHD (CBHD-R)

Patent CN101712809A describes an organic dye and recordable CBHD medium while calling commercial CBHD read-only replicated media. An AACS LA order form lists CBHD (China) Pre-recorded (P) and Recordable (R) options. Conclusion: recordable CBHD was technically contemplated; no evidence shows commercial CBHD-R discs, burners, recorders or consumer authoring chains shipped.

Reconstruction roadmap

  1. Known-good CBHD disc → sector image → UDF analysis → identify video-system files.
  2. Compare against DCA Book 3 assumptions → identify CBHD-specific extensions.
  3. Reconstruct unencrypted/non-protected test material.

Recommended order: obtain an inexpensive domestic disc; obtain two players (Shinco CBHD-9100 and TCL THBD-1008); identify optical chipset (Novatek parts, pickup, servo DSP, RF amp); dump firmware; make a physical-sector image (ordinary PC drives may not suffice); compare with HD DVD; identify an unencrypted or legally accessible sample; locate the DCA verifier; recover CBC/Memory-Tech authoring software; only then attempt home authoring. Before buying repair donors, photograph the pickup label. Untapped sources for disc-structure clues include the full AVSForum master thread and Wayback captures of Joyo-Amazon and Dangdang category pages.

Until a photographed successful burn-to-player test is published, treat Gemini’s DVD+R DL pipeline as an unverified recipe and treat FSM mastering as required for true physical CBHD.

Keeping the disagreement visible

Readers should leave this chapter knowing the research record does not agree. Gemini publishes a full command-line pipeline culminating in an ImgBurn UDF 2.50 burn to DVD+R Dual Layer and asserts playback on Shinco HD-3700U or TCL THBD-1008. Claude and ChatGPT passes found no documented successful burn-to-player case and emphasise that consumer burners write EFM+, not 4-6 FSM. Gemini’s cited sources for the pipeline are LDDb forum threads, What Hi-Fi, Wikipedia and general Chinese burning guides-not a photographed verification on calibrated hardware in the compilation passes.

Directory hypotheses also disagree. Gemini’s CBHD_TS with ITEM_001.AVS, MAP files and CETC_NAV.DAT differs from ChatGPT pass 2’s EVOB and HD DVD Book 3 model informed by DCA documentation. Claude presumed EVO containers from HD DVD lineage. None of the passes cites a directory dump of a real pressed CBHD disc. Home authors who pick one tree without imaging a commercial disc are guessing.

USB first, pressed media later

The only documented realistic home-content route on original hardware is file playback: CBHD-9100 USB for 1080p, TS and MP4 with external subtitles; HD-3700U USB AVI and Ethernet shares. Those paths exercise SoC decoders without claiming FSM authorship. They are the correct first experiment for anyone who owns a player and wants to see AVS on period silicon.

Recordable CBHD media remains a paper trail only: patent CN101712809A for dyes; AACS LA order-form categories for Recordable CBHD; zero evidence of shipped CBHD-R discs, burners or recorders. Listing HD DVD-R among Gemini’s usable blanks does not create a commercial CBHD-R ecosystem. Project C-physical CBHD-still demands 405 nm mastering, NA 0.65 optics, FSM channel encoding and replication know-how of the Memory-Tech/UOD class.

Reconstruction roadmap order from ChatGPT pass 2: obtain a cheap domestic disc; obtain CBHD-9100 and THBD-1008 players; identify chipsets; dump firmware; make a sector image; compare with HD DVD; find an unencrypted sample; locate the DCA verifier; recover CBC/Memory-Tech software; only then attempt home authoring. Skipping to step ten is how myths about burned DVD-9 CBHD discs spread.

Encoding constraints listed for hardware compatibility-closed GOP near twelve frames at 23.976 fps, Jizhun Base Profile Level 6.1, averages of 12-18 Mbps under a 28 Mbps ceiling-remain useful even if the burn step fails. They describe what commercial players’ ASICs expected. Falling back to LPCM or AC-3 when DRA encoders are unavailable matches player backward-compatibility lists. Multiplexing to MPEG-2 TS is consistent with one directory model; EVO/program stream muxing is consistent with another. Researchers should archive both experiment branches with clear labels rather than deleting the “failed” tree.

Project A (CBHD-like disc), Project B (player-accepted image) and Project C (physical FSM CBHD) must stay separated in grant proposals and lab reports. Conflating them produces blog posts that claim “CBHD authoring works” when only Project A file layouts were demonstrated-or when only USB file playback was tested. VCD’s accessibility came from CD physicality; CBHD kept UDF but not consumer-writable physics.

If a researcher follows Gemini’s ImgBurn steps and a player rejects the disc, record the exact on-screen error, whether the volume mounted as data, and whether CBHD_TS.IFO was present. If the player plays the disc, publish model number, firmware if shown, media type (DVD+R DL versus HD DVD-R), and a short video. Either outcome closes more science than another undocumented recipe. Until then, treat burned-media playback as unresolved per the open-questions list.
