I've been trying to back-up wedding crashers (along with my other favorite dvd's) onto my ipod but am having major auido sync issues. I made into a .vob file with DvD Decrypter. I tested this file and it plays perfectly. I then tried to convert the file to .mp4 format using videora, cucsoft, xilisoft, and imtoo. Towards the last quarter of the movie the audio is about 7-8 seconds out of sync. I don't know much about this kind of stuff... that is why I use simple "one click" conversion programs. Any ideas on what might work or what the problem might be?
