NERO didn't like the video file because of the structure of the MPEG2 video. So I ran it through TMPGenc's MPEG tools and then nero 6 accepted it just fine. Once it was encoded with the proper headers and whatever, the option to disable SVCD compliance did appear (non compliant because the mpeg2 file was 720 x 480). I don't understand exactly what Nero didn't like about the MPEG2 stream before I ran it TMPGenc tools, but that did the job. Neal R. Noble
