They're MP4 format. I agree with the use of PSP9 for converting video, it's greatness. Video is really tricky though, you have to make a folder for it outside the PSP folder on the memory stick duo, something like 100MV001 or something to that effect, then a folder inside that named MP_Root... bleh, the program itself makes it so that's all irrelevant info. MP4 files can also be played by quicktime.
