So, How do we make our divx .avi files with high quality AC3 audio? Normally the best we can do with virtual dub is with the MP3 audio set at 320 kbps, But Ive seen higher audio bitrates out there. When I come across them, they have to be uncompressed just to work with them. Virtual Dub doesnt give me an option to set an audio bitrate higher than 320. And what should we set the bitrate for on the video? These divx's im seeing are definately set higher than your standard 910 kbps. Is there a program that will tell me what the video bitrate is on an .avi file
