i've been searching but haven't come across a software program that appears to be widely used and recommended. of course, i hope i'm terribly mistaken. all i want to do is to convert video files (e.g., .avi or .mpg) files into .mp4 or .mov so i can watch them on my iPad. the most obvious answer would be QT Pro but i'm just looking for a solid, free program. hopefully, at least one exists! thanks.
