first of all when I used avi2mov first and was very pleased with it..however after a while it started crash when i tried convert films. I know for sure that my files are not corrupt or anything like that..it just quit. Now my question is when i use divosx tool and make one .mov part and one .mp3 for the sound, how can i put this together? Is it like some application that will let me put the mp3 track on the .mov file?
