I have three avi files from a parade. When I export them to adobe media encoder, the audio only works on one file. I use these settings:
CBR with PCM audio (8mbps with the 25 minute file (the only one that works) and 4mbps with the 60 minute avi file and the 55 minute avi file (neither end up with audio intact).
Set the multiplexing to DVD.
I have used these settings many many times and they have worked great...but not this time.
