now I do have a question I haven't been able to figure out yet. I have
a couple of video/audio sets we did at Walter Reed AMC back in December for
the disabled soldiers. Two sets which individually I can play just fine on
the player. When I try to compile both mpgs onto one DVD, the audio
switches to 44.1 and loses sync with the video. But again, both play just
fine individually. The only difference in video files, it appears, is that
one is set at 8000 kbps while the other is set to 12000 kbps. I can't
figure this one out, so if anyone has a suggestion of something to try I'd
appreciate it.

So these are two separate VOBs with different bitrates? Are you sure
the rest of the settings are the same?

I'd post this in the one of the DVD authoring forae on doom9
