When I preview my video in DVDAs player, if the file is mpg and AC-3 the audio is dropping out. Audio is fine with mpg audio files, I would assume that it's a hardware problem but we know what assuming gets you.
Just to list my hardware
XP Pro
DVDA 1.0 build 160
P4 1.6
1gig ram
7200 120 gig
SB Audigy 5.1 sound card
I can make DVDs without any audio problems, so something in my hardware or software is causing this. Any ideas?

Thanks
Hunter
