The DVD is fine but I cannot convert it. The video and audio lengths are the same; there's no reason it should be doing what it's doing.
Googling is not turning up any useful advice. The closest I've gotten is the beginning and end in sync and the middle out of sync. Sigh.
Edit: Ugh, I got it. The movie is 95% 23.976 with pulldown. Anything encoded by womble is 29.97. It throws off the framerate....
