I would like to take a screenshot of a scene in movie I bought on iTunes, so I could use it as my desktop wallpaper, or maybe edit it a little and post it on a forum I go on. Whenever I try to take a screenshot of the scene I'd like (in full-screen, or the smaller player) it comes up blank. I've tried it in Quicktime, and the same happens. With VLC, the movie doesn't even open. I'm pretty sure there isn't really a problem with my computer; it's just a copyright issue. But is there anyway I can take a screen cap? Thanks!
