is there a way to get music videos onto the PSP in a format that is sized right for the screen? I think it would be pimp, if there was someway to be able to watch a bunch of music videos on the PSP, in a format that has the aspect ratio of the video and the resolution at the right level to best take advantage of the screen.

You know how you can go to Yahoo Music and click on music videos, and watch the music videos in a little small window, is there someway to do the same thing on the PSP?

I know that there are some UMD's that have music video's or concert footage, but I'm more interested in watching videos from all kinds of different artists.
