Can PSP play 1080p video?
Even though your footages may be in different formats and resolutions such as AVI, DIVX, 1080p, 720p, etc., they might not play quite well on PSP, and some of the portions of the films might look distorted or get cut-off from the screen.
Can you play MP4 on PSP?
Aside from movies and music videos available commercially on UMD, the PSP can also play video files from the Memory Stick. These files must be in MP4 or AVI format. Use a free video file converter if you need to convert a video to a format playable on the PSP.
