	Not DRM. I don't know the details, but it's a function of the video 
driver. If the rendering is done via hardware, then the usual screenshot 
won't work. If you have a software renderer, then it will.

	I think some good players have an option to take a screenshot - where 
they ensure it'll get one even if you're using a hardware renderer.
