I converted some files using Nero - the videos played in my DVD player, and were in .DAT format. But when I tried to play them in my DVD player after copying them to my computer and burning them again to a disk, they could not be played. Why? And when I tried to convert a few WMV files to AVI, they would not play in my DVD player. So where can I get a free .DAT To DIVX Video Converter online? Something that converts without loss in quality or clarity of my videos. Can somebody give me a link? PLEASE! Thanks.
