The PSP only accept MPEG-4 videos. If your video already is MP4 format and your PSP firmware version is below V3.0: 1) create a folder named "MP_ROOT" in PSP memory stick 2) inside that folder create an "100MNV01" folder, and a "100ANV01" folder. 3) If your video is MP4 format, rename it with this format "M4VXXXXX.MP4", rename the thumbnail with this format "M4VXXXXX.HTM", XXXXX are five random numbers you like. 4) If your video is MP4, save it in the "100MNV01" folder, but if its and AVC video, save it in the "100ANV01" folder. If your PSP firmware version is above V3.0 1) create a folder named "MP_ROOT" in PSP memory stick 2) inside that folder create a "Video" folder 3) then copy your MP4 file to this folder, done Also I want to know which software did you use to convert? Is there any thing wrong with your convert software?
