some of my .AVI files are in PAL, and when I go to burn those files, it asks me if I want to convert to NTSC. Those are the .AVI files that can burn to a dvd properly. The .AVI files that are already NTSC, and dont need to be converted are the ones that are having the audio video sync issues. I am asking if there is a way to change the .AVI files that are NTSC to PAL (without burning to dvd)? If they could, then when burning, toast asks me to convert or not, that might work.
