I've been having an a/v sync problem when converting .vob files to .dv using ffmpegX. The audio is a half second or so behind the video. The source video was recorded from tv on a dvd recorder. Oddly, three of the .vob files from the source converted ok, but two have the problem. I've gotten some suggestions from Major, but so far nothing has helped. Anybody know of a fix either in the conversion process or post process?
