Can't I just get some software to handle all that? My DVD player can play data disks anyway, so I don't need to write them out with menu screens and things.
Or do you mean converting them for the IPAQ? Already done that, I found a good bit of software that takes AVI files, and resizes them. Important for the IPAQ as the originals would be too big to store, and the screen size is only 320 x 170 anyway.
