I was pretty sure you could put whatever video you want on the ipod as long as it was mp4 format. you can find mp4 convertors online, so any video could be played on it. I go to bladevids.com for my PSP movies, and they list movies for the ipod video too. Check that website out. They have whole sections for ipod movies to dowload onto it.
I can give you more details about it once my girlfriend opens up the 30gb video ipod I got her for christmas.
