ok so i rented good luck chuck 8 hours ago on itunes and then i pressed play and it wont play! it charged my account for it but it wont work then it freezes up itunes. one time it sorta played.. like i saw a picture from one of the scenes and then it froze up. the farthest i can get now is the first 2 seconds then it freezes. im getting very very very sick of this and i payed good money to see this so i want to see it. what am i doing wrong?!!?!?!?!

is it because im watching it on computer not ipod. cuz i have an ipod without video so i can;t do that. and dont tell me its because my itunes isnt updated cuz i updated it today just because i knew i'd have to for the movie
