You can try the usual suspects - zip, bzip etc, but you won't get far. programs that reduce the size of DVD9 so that they will fit on a DVD5 usually requantise the stream, I am not sure what that means, but it is much quicker than transcoding to another codec like xvid. xvid will, of course, give you a much smaller avi file. the analogy with flac is not really appropriate. flac is a lossless compression, you start with an uncompressed wav file and end up with a losslessly compressed audio file. A DVD is already lossy compressed to mpeg2, so it is not logical to make an analogy with flac. As I said, you can requantise, but of course you lose something... > - Grant -- gentoo-user@gentoo.org mailing list
