Q: I subscribed to "The 1UP Show" RSS feed and had it download overnight. When I go to it under videos it says "unsupported movie type" or something like that. It is a mp4 file and if I run it through PSP Video 9 it'll play. But I'd like to to play right off the bat. Any clue? I'm also having the same problems with "On the Spot" from gamespot.com. Also what are the restrictions on mp4 files for the PSP?
A: The PSP has some peculiar restrictions with video playback. The two you should focus on are video resolution and bitrate. Videos are limited to a maximum of 76800 pixels (320x240, for example), and a video bitrate of 768kbps. You should make sure that videos that aren't named in Sony's proprietary Memory Stick format (MAQ, M4V) are placed in your Memory Stick under a folder called "VIDEO."
Unfortunately, it appears that "The 1UP Show" is now encoded at a much higher resolution than the PSP is allowed to play back. You may want to download PSP-compatible files directly from The 1UP Show website.
