Here is a Linux version: http://home.t-online.de/home/ritzert/videocd.html The VideoCD format was never really publically documented back when it was popular, and there were some programs that reverse engineered it that Phillips went after (MPegTV?); I remember that the last set of Commodore hardware had a license for it, and it was held as a closely guarded secret at that time. It's actually pretty trivial; you need to be able to read the full sector, instead of just the smaller "formatted" data portion of it; this is already supported in an CDROM hardware that can read raw audio off a CDROM, which is pretty much any CDROM drive since the first one that could do it in the SGI Indy, and the first one you could legally buy in the U.S. seperate from a system (the Toshiba 3401B; I have one, of course). Probably, you are talking about a very old Video CD (CD-i), which is Green Book standard. Panasonix and Matsushita CD drives can't read these, so it might just be a difference in hardware. If you are talking about a newer one, then it's a White Book standard, or, the newer Video CD 2.0. To get a copy of this, you have to be a licensee from Phillips of one of: o CD Information Agreement o Software Dev Package o CD Disc/Player o VideoCD Disc/Player See: <http://www.licensing.philips.com/includes/download.php?id=162&filename=sl00272.pdf>; -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
