Error Message Help
You've encountered error message C00D1199 while using Windows Media Player. The following information might help you troubleshoot the issue.

Cannot play the file
Windows Media Player cannot play the file. You might encounter this error message for one of the following reasons:

The file type is not supported by the Player. For a list of file types (formats) that are supported by Windows Media Player, see the table on supported file types in this topic.

The file type is supported by the Player, but the file was compressed by using a codec that is not supported by the Player.

Your sound card or sound controller is not configured properly. Try changing the audio output device associated with the Player.

To change the audio output device
Click the arrow below the Now Playing tab, and then click More Options.

Click the Devices tab, and then double-click Speakers.

In the Audio device to use box, select a different sound card or sound controller.

The file type is supported, but you are trying to play it in a way that is not supported by the Player. For example, you might have tried to drag a DVD file with a .vob extension from a DVD to the Windows Media Player icon. Or you might have tried to open a .vob file by clicking Open on the File menu.

You are trying to play one part of a multipart file. Use a newsreader or other program to combine the files, and then try again
