I want to change it from TM avi into a DivX 5 avi so my friend, who uses linux, can see it. YOu see, TMplay won't work under linux, and he wants to see the Sonic CD ending from Sonic Jam. I would convert to DivX 5 on the fly, but my computer has a nasty habit of dropping frames when converting to divx 5 unless its a raw, uncompressed avi, thus I need to first convert it to an uncompressed avi.
