I've been putting a lot of my movies onto my ipod recently and haven't had any trouble. I create just one large ISO file (I don't split the movie into chapters or anything, just one big file) and I remove all of the processing except 0x80 english audio. From there I use videora ipod convertor to change it to an mp4, simple enough. however, some of my movies end up with the audio lagging behind the video (only two i've noticed so far are the Matrix and Nightmare Before Christmas), and was wondering if anyone knew how to fix this for these situations? I opened the .txt file that is created and saw that there is a delay time listed for the audio of these movies, but don't know how to fix it. any help is appreciated!
DVD Decrypter isn't creating the delay...this is a converter problem, I would try a different program to convert your video to MP4.
