I enjoy using my PSP as a PMP, but for the life of me I can not figure out Sony's goofy video size restrictions. The max cropped video in a 16x9 is 480x272. I can go to a higher resz of 720 but it has to be 720x480. (Basically a DVD resolution without the cropping.

Is there anyway to edit a cropped video; say 720x400 or 640x352 and make it playable on the PSP without encoding?
