help! how to delete movies from your quicktime list?
 

do any of you guys know how to delete movies from your quicktime list?
I have a ton of porn and i need to delete b/c my dads taking the comp in so we can see y it's such a piece. The technical person is a lady and it would be awkward. I downloaded the movies from LW but since i can't get into LW i can't delete them from there. Unless you guys know what to do, im screwed!

PLEASE HELP ME
