Q: Can't play movie on iTunes - from PC

Hi, last week I downloaded a movie from teh iTunes store but have gone to play it and it will not play.

First msg is that I need QuickTime Player.  So I downloaded that.

Now I open QuickTime and browse to open the movie file, by going to Libraries, Music, iTunes Media, Movies and then select the movie.  Now it says No items Match your  Search.

Any ideas what I am doing wrong?

Thanks

John
