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.
