Hi,
I've just tried both preparing and mastering a Vegas project in
DVDA. The preview disk function works correctly--that is, selecting scenes begins playback of both video and audio at the correct points.

However, when I try "Make DVD", the audio is only present on the Main Menu screen whether I "prepare" or "master".
The video is an .mpg file and the audio is .ac3 format.

What am I doing wrong?

Thanks,

Michael
