First of all, i'm running on a Mac not PC. Um, I have the video that I need to put on the PSP. It's a .mp4 scaled sown to fit the PSP screen. I put it in the Video folder and it didn't show up. So I put it in the MP_ROOT/100MNV01 and it showed up but it said, Unsupported Data. Am I doing this wrong? It's driving me nuts!
