I have a problem when I have to select the audio input source for my vob files when I use TMPGEnc DVD Author. First I used "VSO DivxToDVD" for my mpeg and avi files and made them into VOB files. Then when I add the video in DVD Author, I can select the video file but there is no audio to select, even when I click the "Browse" button for the audio input source, there is no audio there. This only happens to some files not all of them. I do know all my avi and mpeg files have sound because I play them in PowerDVD and other players. What am I doing wrong here? DivxToDVD should have created audio for all my files.....sigh.
