Yup as he said - the video is overlaid therefore it doesn't exist to Windows in the case of pressing the "Print Screen" key. All you'll get is a black/blank screen capture.
Goes something like the picture is overlaid just prior to being viewable on the monitor therefore Windows doesn't know its there.
The DVD player itself usually has a hotkey to allow you to take screen captures.
