Check out bittorrent sites, limewire, or somthing like this http://www.youtube.com/watch?v=g9los-zo7…
You might need to convert your video, so google PSPvideo9.

hey.
i wanted to do the same thing but it is not possible. you can buy/download limewire and use it to bring the music videos or music or watever into your computer. then use psp video 9 to convert the files so they can be used on your psp. i have psp video 9 and it is probably the easiest thing out there to use. heres a link. http://www.pspvideo9.com/Download/
for limewire or any other dowloading program you basically have to buy it. they usually range from 25 – 50 bucks.
good luck!
