CVD Compatibility

[stevendm]

I know that most DVD players will play VCDs. A lot of them will play SVCDs (probably 50%). Approximately what percentage of DVD players will play CVDs?

TIA

Any dvd player that can play SVCD should be able to play CVD. The exact details may be a little sketchy but it seems that Svcd players are required by law to also support CVD. Even if this was not the case all dvd players already support CVD's half d-1 resolution since it also complies with the dvd standard so for the most part it wouldn't be a problem anyway. The fact is that I think you would be very hard pressed to find a SVCD compatible dvd player that didn't also support CVDS. So as far as the % that support CVD, your guess is probably as good as mine but I do think it is probably more than %50.

As what adam stated.

CVD (invented by C-Cube) was one of the contenders for the next format after VCD and "CVD" players + discs were actually produced for a while a believe.

When the SVCD standard was ratified, it had to accomodate CVD so a SVCD player is supposed to be able to play CVDs.

In any case, there is relatively little difference between the two standards and as adam has already mentioned, DVD players (rather than SVCD stand-alone players) already support the framesize of CVD.

There has never been a post that I can recall that mentioned that a particular player was able to play a compliant SVCD but not a compliant CVD disc (48 kHz audio is not compliant for those people with their cursor over the reply button! ).

I have to say once again that I recieve many US emails, with problems about NTSC CVDs. Standard CVDs that is (44100khz audio, 352 X 480 @ 2520CBR).
In theory I know that it shouldn't be a problem, but in praxis so many reports show me that there is. Since myself can't test it, I have to mention it in every single reply for CVD.

Okay, I wasn't aware of that (but then I don't really follow CVD development much).

What kind of problems are common SatStorm?

Statering picture, non pan and scan picture and sound with broken picture most of the times.
Don't mention that anti-alizing picture most US users reports to have (never saw it myself...). But this has to do with the quality.

Personally, I believe they doing something wrong, or certain well known in US Standalones don't like CVD.
But from the other hand, you never can be sure without test it yourself!

I believe only the grow of reports for this matter in VCDhelp's DVD players Compatibility list gonna show the true compatibility of CVD.

So US members, keep reporting!

I have to agree with SatStorm's statements. Many ppl have reported problems with players imported into the US. I also note that in Europe, Asia and in the Asia pacific region- the CVD logo and lettering is appearing on more imports (the China disc, not the Spanish format) while the US market does not seem to advertise this logo much if at all.

I don't know the reason but I do know that it is not down to c-cube
or ess - I have seen Apex/VVD clones that do not play CVD but play
SVCD just fine (c-cube technology). Some of the latest cheap Chinese and Korean brands won't even play VCD!

I'm waiting for the day when oem manufacturers
like Pioneer wake up and demand multiformat readers from their suppliers. We all should have off the shelf HTPC's by now!

Something to think about is how many player OFFICALLY support SVCD? I would say that's about half of the number that PLAY svcd's. I would say that the majority of those that OFICALLY support SVCD probably play CVD.
