make sure Windows Media Player (or any other DirectShow application) is closed before installing.

А можно сей Player на SP1 поставить?

Why do I get error C00D11BB when I try to stream content?

Error message: "Windows Media Player cannot play the file because the specified protocol is not supported. If you typed a URL in the Open URL dialog box, try using a different transport protocol (for example, "http:" or "rtsp:")."

Windows Media Player can't play the file because the specified protocol is either not supported by the Player or not supported by the server.

If you encountered this error by clicking a link on a Web page, the link might not be valid.

If you encountered this error by typing a URL in the Open URL dialog box, try opening the file by using a different transport protocol (for example, "http:" or "rtsp:"). The following list shows the protocols that are supported by the Player and examples of the correct URL syntax:
•

mms://server/filename (for example, a file with a .wma, .wmv, .asf, or .mp3 extension)
•

http://server/filename
•

rtsp://server/filename
•

mms://server/sami.asf?SAMI=http://serve ... i_demo.smi (SAMI file)

If the Player supports the protocol that you used in the URL and you still can't play the content, verify that the Player is configured to use all of its supported protocols.

To configure protocol settings

1. In Windows Media Player, on the Tools menu, click Options.

2. In the Options dialog box, on the Network tab, in the Streaming protocols area, select all the protocol check boxes (Multicast, UDP, TCP, and HTTP), so that a check mark is displayed in each.

Note that the supported protocols can be used only to stream digital media files. Windows Media Player cannot be used as a browser.

If the above fixes don't work, you can rename the networking information folder for the Player so that it can rebuild its networking information files after you restart it.

To rename the Player networking information folder

1. Close Windows Media Player. (To do this, on the File menu, click Exit.)

2. Click Start, and then click Run.

3. In the Run dialog box, type the following (exactly as shown):

%UserProfile%\Local Settings\Application Data\Microsoft\Windows Media

This step opens the following folder on your computer:

SystemDrive:\Documents and Settings\UserProfileName\Local Settings\Application Data\Microsoft\Windows Media

4. In this folder, rename the folder 10.0 to 10.0.bak. For more information about renaming folders, see To change the name of a file or folder.

5. Start the Player and try to stream the content again.
