The Industry Standard - Sony's PSP movie plans form around US launch:
"Sony Computer Entertainment Inc. (SCEI) will begin to realize its plan to expand the PlayStation Portable (PSP) platform beyond games into prerecorded movies and other video next week when it launches the PSP in North America.
The upcoming launch on March 24 will be the first for the PSP outside Japan, where is was launched on Dec. 12.
At present only gaming software is available in the PSP's UMD (Universal Media Disc) format. UMD is a 6-centimeter optical disc inside a protective cartridge. Each 10-gram disc can hold up to 1.8G bytes of data. That's significantly less than a DVD-Video, but by using more advanced compression and cutting DVD extras such as out-takes, SCEI can fit a movie on a UMD disc."
