final fantasy advent children question ?

Yes, UMD is the format the PSP uses.
I can't actually remember where i heard it, and lately my favorite use for my PSP is emulated games.

Also, I'm not cool enough to have a portable DVD player, and i enjoy watching things in the palm of my hands. If i did have a portable DVD player though i'd prefer that...

Well, "cool" enough is the wrong word. I won it in a prize give away for donating to something. Ii was totally out of the blue. But I more meant that you couldn?t watch a UMD on anything but the PSP, so you would have to have two copies of the movie if you wanted to watch it normally.
