I rendered separate video (main Concepts) and stereo AC3 (2/0 , dialog nomralization -1db, 48k) out of vegas 4 and when I bring up DVDA (1.0 230) build I get no AC3 playback. I went back and rerendered the audio as a .wav and that plays back fine in DVDA.

The Sony Vaio K37 has the Realtek audio card. p4 3.0, 1gig ram.
Any Thoughts.
Thanks....it's a simple single camera family wedding video..the only plugin is wavehammer across the master audio output in vegas.
