Can be movies, shows, episodes. Should be like a Disney show or something I probably heard of.

I have already seen all of the Bring It On movies. Are they any more cheerleading movies out there? Just wondering cuz I thought they were pretty cool.

I use iTunes, do I have to buy movies from there in order to add them to my iTunes library and sync them to my iPod or can I just add any movies I already have?
Please Help!
