I have found a way to get synchronised video when they are converted to DivX / DVD. If it has answered before, please delete it, as I just searched the forums and it seems many people are having this problem: Improper VBR Audio means that obviously, the audio stream is an mp3, with variable bitrate. To come around this problem all you have to do is simply: 1. Open up Virtual Dub, then your AVI. Click OK for that inconstant VBR audio thing. 2. Now go to Audio, and select Full Processing Mode. 3. Go to Compression. Now select AC-3 ACM Decompressor 4. Go to File > Excract Wav. 5. This will take about 1 minute to extract. It extracts to 1GB. 6. Now when you encode your file to mpg, (suggesting you are using tmpg) Just select the video file as the normal AVI, and then select the audio file as the uncompressed WAV. **NOT the same as the avi file** This should solve the syncro problems. I have done this to 4 AVIs with the VBR problem, and all have been in sync. Enjoy.
