You press Alt + Prnt Scrn. Oh, and if you're playing it with windows media player, you'll also have to go to Tools > Options > Performance. When you get there, there should be a bar at the bottom of the page for "Video Acceleration." Move the arrow to "none" otherwise the screens won't work. So anyway, after you press Alt+Prnt Scrn go to your image editing program (like photoshop or PSP) and open up a new file. Then press Ctrl+V to paste your screen.
