    OK - Apple specs say the Touch supports "640 x 480" resolution. (4:3)

    Now, explain how that works, given that the screen size is 480 x 320 (3:2 widescreen).

    If you put a 640 x 480 vid on there, does it get chopped?

    If we're encoding, it's rare to scale video down to 480 x 320 - one or the other dimension is usually smaller. But if we do it bigger - say 480 x 352 - will it get chopped?

    (I realize iTunes videos are sold at 640 x 480, so Apple needs to support them - but practically, how does it look?)

    You get letterboxes if aspect ratio is too large (top and bottom) or too small (on the sides).

    If you double tap the picture, it will zoom in to eliminate the letterboxes (but a bit of the picture gets cropped out.)
