I have imported VOB files from a DVD and can play them in the source window with audio. When I drag the same file to the Timeline the audio fails. I can see the audio has loaded into the Audio track and can see that I have sound up to about a -12 level. I have had success in other similar projects. It should be noted that I did not capture the video rather I simply imported files using the media browser. In reviewing the misc. forums it appears that there are some issues with sound and video importing VOB files but it seems like there should be a simple solution to my immediate problem as I can hear all when I review in the Source Window.
