I have a bunch of AVI files which are in iTunes via QT reference files. Is there a format that would work on an iPod touch/iPhone AND still be good quality for viewing on computer or ATV. I see iTunes has "Create iPod or iPhone version" and "Create Apple TV version" under the Advance menu so I presume you must create separate files depending on where you want to view them. How viewable are the iPod versions on a computer? Or does most people creates separate iPod-only versions? If one format can work on the computer and on iPods then I may spend the time converting them all, otherwise I'll just keep the system I have know since I have no real desire to watch them portably. Also, what is the quality of videos converted for Apple TV?
