You have a multiple bit rate (MBR) file or a live stream that contains more than 32 media streams. You try to play the MBR file or the live stream in Windows Media Player on a computer that is running Windows Vista. However, Windows Media Player cannot play the MBR file or the live stream. Additionally, you receive error code C00D11B1.

Note: This problem also occurs when you use Windows Media Player on a computer that is running Windows XP.
