wouldn't the avi file be huge? I'm not a video expert, but I thought the point of mpeg4 was the compression to make the file smaller. Does the iPhone or any other phones play avi? Also when you use DM to transfer the video it resizes for your phones screen also making the file size smaller (assuming the resolution of the source was bigger than the resolution of the screen). I have used it to transfer a few videos and did not seem to take all that long.
