I authored a dvd using Ulead DVD Workshop 1.3, and 80min minutes into the movie, the audio goes out of sync. I re-played the original file on my computer-but it's fine. I then previewed my project in dvd workshop-no problem. The only thing though, I used an mpeg file with Mpeg layer audio, for which I got a msg from dvd workshop saying this is not standard dvd ntsc audio format.

Help!!!
