I have a bunch of .avi movie files on my Mac that I am converting into .mpeg-1 files and then burning onto a disc so that I may watch them on a regular dvd player. I am using ISkySoft Media Converter to convert the .avi files to .mpeg-1 files. The conversion always works fine, and the new mpeg-1 files work great, and the audio is always in perfect sync. However, when i try to burn the files using Toast Titanium, the resulting movie plays fine but the audio is always a few noticeable seconds off. What can i do to fix this problem?
