    Yes, it works on some DVD players. The reason why, I think, is because both SVCD and DVD video is in the MPEG-2 format. Although a standalone player might not recognize an SVCD disc (the manufacturer didn't or couldn't include SVCD support), it could still read the video file. The SVCD header trick replaces the header at the beginning of the MPEG-2 file that identifies it as MPEG-2 with a header that claims to be an MPEG-1 file. The DVD player sees this fake MPEG-1 header and tries to play the file. The key is that the player chooses a decompression routine independent of what the header is, so the file is actually decompressed with the player's MPEG-2 routines. This works only on those players that don't use the header to select a decompressor and support different MPEG-2 bitrate.

    As for how to do this, a guide I found at VCDEasy.org explains it best in my opinion:

    Good luck with it! Post again if you have any more questions.
