I can't remember if it was this forum or another one where someone suggested dragging the VOB onto your harddisk, right clicking on the name and 'renaming the file' with a .avi extension, try it and see how you get on. I think the problem with the audio is there is also a much smaller file along with the 'biggie' and it contains some kind of information that gets the audio working so maybe you need to transfer both.
