FIX: You receive error code C00D002B when you start a publishing point that uses an MBR file or a live stream that contains more than 32 media streams in Windows Media Services on a computer that is running Windows Server 2008

You have a multiple bit rate (MBR) file or a live stream that contains more than 32 media streams. On a computer that is running Windows Server 2008, you configure a publishing point in Windows Media Services to read the MBR file or to retrieve the live stream as source content. When you start the publishing point, you receive an error that has error code C00D002B.

Note This problem also occurs in Windows Media Services 9 series on computers that are running Windows Server 2003.

This problem occurs because a variable that defines the average bit rate for each media stream is hard-coded to 32. The variable is in an Advanced Systems Format (ASF) header object. When the number of supported media streams exceeds 32 in a file or in a live stream, the Load function closes the connection to the media streams.
