MP3 players: Zen vision M compatibility

Zen vision M compatibility

can you use the vision M with itunes? im sure thats a stupid question but i'm in a dilemma right now with which one to get. i have all my media in itunes right now and i really dont want to go through the hassle of converting and moving files around and stuff ( i'm sure thats a pain in the ass)

also, can i put full length movies onto a ipod or visionM? if so, how do you do it because i would love to have the option to watch some of my favorite movies on the go...

thanks in advance for the help.
