The PSP As Marketing Tool
If you're looking for more to do with your PSP, Kotaku has a few suggestions for you. Music Videos, Advermovies, and AtomFilms are all being formatted for Sony's new handheld. From the article: "...AtomFilms is making some of their free movies available for PSP download. Interestingly, Sony actually paid AtomFilms to make this happen. In return, AtomFilms is reporting download stats back to Sony."

Going to the link through Google News gets by the NYT registration.
It's formatted to fit on the PSP's screen, but the files are just normal MP4 files. You can play them on your PC with video players like VLC.
Not particularly relevant to the AtomFilms material, which is already available to download, but some of the music videos mentioned in the article are only otherwise available in streaming format - these PSP downloads are a good way to save them to your PC.
