I need to convert my video files to AVI so they will play on a portable dvd player, but when I convert the files I get a blank white icon with a folded corner and the file will only play the audio, no video. When I highlight it the file Name is xx.avi and file Kind is Quicktime file, and the icon is a black square with a note on it like an iTunes file. Anyone know how I can convert my videos to avi format that will play the audio and video together properly?
