>ensuring that there is no way whatsoever to get the audio or the video I await the patent on how to DRM photons. Relating to the rest of your points, I am not convinced that it is that difficult to mix protected and non-protected graphics. The untrusted software tells the graphics card a square region of the screen where the movie should be played, and streams the cipher text to the card. When the graphics card goes to render a frame for the physicall display, it first renders the the protected content, then renders any unprotected content from the software. Where the two overlap, the protected content simply gets hidden by the unprotected content. Obviously, all of this rendering would happen in an undisplayed buffer, so the user only sees the finished frame.
