    Do you mean the video bitrate of the game video or did they release some actual movies for the CDI on CD ?

    And I don't know about movies, but I do own some old music CD's that also have music videos or live videos of songs on them that only play on my laserdisc player.
    But the audio part will play on any standard cd player.

    also besides vcd dvd and divx movies was there any other movies that came out on compact disc
    Well, DVD never came on on compact disc, hence the name DVD........

    Like in every other circumstance, the exact video bitrate will depend on the length of the movie.

    They did release some actual movies on CD-i, which predated VCD. However, they quickly switched to just creating movies on VCD, because the VCDs were playable on CD-i players AND VCD players, but the CD-i's were only playable on CD-i players.
    AND, not all exisiting CD-i players had the FMV ("full motion video") add-on cartridge, so those wouldn't be able to decode the video. VCD players of course had that built-in.

    The spec for CD-i FMV was not IDENTICAL to VCD, but it was close enough. I have that info stored in my CD archives and could look it up, but don't think that's really necessary, since you cannot CREATE a new CD-i.
    The equivalent - VCD, is 352 x 240 @ 29.97Fps or 23.976 -progressive (NTSC) or 352 x 288 @ 25Fps - progressive (PAL). All are encoded to MPEG1 System Stream (ISO 11172) Containers, using MPEG1 video @ 1150kbps CBR and MPEG1-Layer2 audio @ 224kbps CBR. Since the CD-i format wasn't really tied to national video systems like VCD/DVD/BD is, but was more computer-oriented, it probably did use ~384 x 288 (but at 4:3 DAR) at least as part of its spec. That sounds about right. Bitrate was also right around 1100-1200kbps, just like VCD. Remember, those needed to play on standard 1x CDROM drives, and that is the bitrate that one would get from a MODE2Form2 sector readout - ~1361 kbps (2324 user data B/sector, 75 sectors/second) and no higher.

    @jamespoo, I'm assuming you meant PHILIPS' CD-i movie, not Panasonic. Panasonic made the competing 3DO format.

    I've got an SVCD of Rambo III from Malaysia that was a commercial release there. It's spread out over 3 discs. It's been a long time since I looked at it, but I remember that it played OK in my DVD player but the directory (or "folder" if you prefer to use that term) names weren't quite right for SVCD. It has SVCD type video but it was built more like a VCD in terms of directory names and contents. It was a bit bizarre. SVCD never really took off and there was a competing similar format that also never took off called China Video Disc or CVD, which should not be confused with the laserdisc CDV variant alluded to by Noahtuck. CDV was probably on something like a CD but very little is known about the format as it wasn't popular and computers can't read them or create new ones. I have a laserdisc player and I've got some CDV discs, but all I can tell you is that the underlying disc is PROBABLY a CD because DVDs didn't exist at the time, but as I said since computers can't read these discs, I have no way to know what the disc is actually made of.

    @jman98 & jamespoo,
    the CDV that you were thinking about is a Hybrid Digital+Analog disc. On the digital side (1st session), it is a standard AudioCD with 1 or more tracks. On the analog side (2nd session) it is a standard Laserdisc video. Being analog, that section is totally UNREADABLE on digital computers. Only way to get that into a computer would be to use a Laserdisc player and Analog capture card.
    There are 2 forms of CDVs: the "Video Single" that was the usual 12cm disc form factor which would play the audio in standard AudioCD players (and the video in LD players), and the "CDV EP" which was really a smaller form Laserdisc (about the size of a 45rpm record, ~9-10") that only played in LD players (whether the digital audiocd tracks or the analog video title).
    This is not to be confused with later LD video titles that included digital soundtracks (AC-3, DTS or LPCM).
    For the 1st session only, the disc is, for all intents and purposes, a standard AudioCD both in physical makeup and in logical structure.

    @jamespoo,
    There have been OTHER disc formats that have included video footage: CD-Extra/EnhancedCD, WMV-HD, 3DO, etc., but all of them are also-ran formats that never really got off the ground (though some were and still are pretty cool and should have had a better life). I can fairly confidently say that ANY title that was put out on them was also put out on a more popular format: LD, VHS, VCD, SVCD, DVD, HD DVD, BD. Heck, even RCA Selectavision CED discs had a better run.
    So you're not losing anything by not having those titles in that format.
