i want to completely remove the audio from a dvd film and then insert an mp3 audio track that is exactly the same length as the film. can anyone point me to a guide on how to do this? also, i have access to sony vegas, and i ripped the dvd to disc using the 'file' setting in dvd decrypter (video_ts folder). i could go back to the original dvd if need be, if the vob files arent the ideal way to go about things. thanks in advance for any help!
