What editing codec did you use? Normally, I’d Export QT Movie with Current Settings and DVD Studio Pro Markers selected. Then I’d drag that file into Compressor to make the mv2s and ac3s.
Are you viewing the video on a monitor during the edit and when you play the DVD. Watching it on the computer is not the best idea.
