SYMPTOMS
You may be unable to play Digital Rights Management (DRM)-protected content in Microsoft Windows Media Player 11 on a Windows Vista-based computer. When you try to play DRM-protected content, you may experience the following symptoms:  You receive the following error message:

0xC00D11B1 - Windows Media Player cannot play the file. This can occur when another program or operating system component encounters a problem but does not communicate the nature of the problem to the Player.

 Windows Media Player may abruptly close after the license for the content has been downloaded.



CAUSE
This issue occurs if the computer is using a Windows XP Display Driver Model (XDDM) graphics adapter driver.



RESOLUTION
To resolve this issue, you must install the most current version of a Windows Display Driver Model (WDDM) driver for the video card or for the integrated video device in the computer. To do this, follow these steps:  Make sure that the copy of Windows Vista is a validated, genuine copy. Visit the Genuine Microsoft Software page, and then click Validate Windows:

 Make sure that the video device has the most current WDDM drivers.

For a list of video cards that contain a graphics processing unit (GPU) that supports WDDM, visit the following Microsoft Web site:

Run Windows Vista Upgrade Advisor to obtain information about hardware that a computer may require to support the Windows Vista Aero theme. The Windows Vista Aero theme requires that the computer's video card uses WDDM drivers. To run Windows Vista Upgrade Advisor, visit the following Microsoft Web site:
