Cheers, but I disagree. Lets forget the technical explanations, a practical test will determine the reality. Use a DV cam to video something square. Is it still square when you view it at 720x480 on a computer? Is it still square when you convert to ipod using qt703 ipod export? Is it square on the ipod's screen?
I dont think its splitting hairs because black bars onthe ipod are annoying, things at the wrong aspect ratio are annoying, and no videoblogger wants to do it wrong for ages and then have to go back later and reencode perhaps hundreds of clips.
