I'm getting a pop in the audio track when the video ends, and before it retruns to the main menu. I've checked the audio track itself and it is clean, I've re-rendered and done all I can think of. Any thoughts?
Can you try a completely different audio file fo the same length as your video file (stretch or shrink it as needed). Then retest. If the issue goes away your issue is with the encoding of the original audio file. Hope this helps.
