Need help in powerpoint, projector, and movies.?

I have an ignment, using powerpoint and I would like to insert a movie so that I may stand out cuz almost everyone has already presented theirs besides me. Well, the movie I wanted to insert appears rather small in windows media player.... its .wmv and it's a little blur when I go full screen. Well, the thing I'm worried about is, will the movie go totally blur when I present it with a projecter cuz u see, everything appears larger on the screen. Can someone give me an answer fast? I do not have a projector at home so HEL~P!
