I have an MPEG2, 2 hour concert encoded thru Vegas. I had the client give me 6 channels of audio had them synced up in Vegas. I pointed them to their respective speakers etc. I rendered the audio out as an AC3 one file. How do I make a Play All and have the audio and video together?
If the AC3 file has the same name and lived in the same directory at the MPG file, then DVDA should include it automatically when you bring in the MPG. If it didn't, simply click on the "..." button in the audio section of the object properties for the movie and select the appropriate audio file.
