Consider the following scenario. You play a video in Microsoft Windows Media Player in a multiple-monitor configuration. Then, you switch to a different logged-on user account by using the fast user switching (FUS) feature in Microsoft Windows XP. When you switch back to the original user account and try to restart the video, you experience one of the following problems:
  • You may receive the following error message:
    Windows Media Player cannot play the file. The player might not support the file type or might not support the codec that was used to compress the file. 0xC00D1100
  • Windows Media Player does nothing at all.


When you switch out of the current environment, the display device becomes unavailable to the Video Mixing Renderer (VMR), and the video stops. When you switch back, the VMR queries Microsoft DirectDraw (DDraw) to determine whether a device is available. In a multiple-monitor configuration, DDraw returns an error instead of telling the VMR that a device is available.


To work around this problem, exit and then restart Windows Media Player.
