I downloaded some .mp4 videos on to my PSP. As far as I was aware, these should work on the PSP. However, whenever I try to play them I get the message: Data not supported. I'm thinking that either I've placed the files in the wrong place or they're the wrong format. On my PSP they're in PSP(E/PSP/VIDEO. Or maybe it's the wrong file type all together, on properties it says MP4 video (.mp4) If it is the case that its the wrong format then I'm going to have to convert them. I've seen that they're quite a few video converters for the PSP around, so which one would the best? Thanks in advance.
