I did a file analysis of the video the unit records and plays back. Here are screenshots of that. It's using a German MP3 audio codec from Fraunhofer.
I need a program that will do an Xvid MPEG4 with the same kind of MP3 audio codec. Any ideas on what might work? If you look at these settings, they are totally different from the sample file. And these are from videos I made with the unit.
