Why would he have to split it? If the starting aspect ratio of the avi file is 2.35/16:9 (I think 2.35 is 16:9) and you use SUPER and choose 5:4 aspect would that cut off some of the image or just stretch it? When I go to burn the new file do I use Express 6 or Vision 3? If I use either one does it recode, the whole reason I want to use POWER is so I don't have to turn on burner and keep it on for one movie to take 2hrs to recode. Probably have more questions but I don't want to flood you. ty
