SYMPTOMS
When you attempt to render an MPEG stream from a NetShow Theater Server using the Windows Media Player, the following error appears:

Protocol mismatch error.

(Error=C00D0012)

Windows Media Player cannot open 'nsm://theater/jazz.mpg'. Please verify that the path and filename are correct and try again.

(Error=C00D0012).



CAUSE
This issue may be caused by the use of either a beta version of NetShow Theater Server or a beta version of the Windows Media Player.



RESOLUTION
There was a protocol change between the beta-4 Theater Server and Windows Media Player release and the final NetShow Theater Server 3.0 and Windows Media Player release. After installation of the released 3.0 version of NetShow Theater Server, you must use the released 5.01.52.0701 version of the Media Player to render a Theater Server stream.

The Windows Media Player download file that contains the NetShow Theater Server decode filter was last named, Mpfull.exe. After you install the Windows Media Player, verify that you have installed the Windows Media Player that contains the NetShow Theater decode filter by searching for the file named Qnspro.dll, which is found in the default installation directory of C:\Program Files\Windows Media Player\. The version on the file should be 3.0.0.2700.
