Consider the following scenario:
On a computer that is running Windows Vista, you play a video that requires that Certified Output Protection Protocol (COPP) is used for playback. For example, you play a video from a Blu-ray Disk.
The application that you use to play the video uses Video Mixing Renderer 9 (VMR-9) to display the video.
You use two or more monitors, and you extend the desktop.
The application is running on the primary monitor or on the secondary monitor.
In this scenario, the application does not play the video. Or, an error occurs in the application.
When an application uses VMR-9 to create a COPP session with a video driver, an error always occurs in the COPP session. The error occurs even if the video driver fully supports COPP.
