SYMPTOMS
You apply a windowless skin such as the Revert skin to Microsoft Windows Media Player 11, to Windows Media Player 10, or to Windows Media Player 9. However, after you apply the skin, certain kinds of video content do not play.



CAUSE
This issue occurs if the video is encoded by using a YUV-based pixel format. In this scenario, Windows Media Player incorrectly processes the video content.

This issue does not occur if the video is encoded by using a RGB-based pixel format.



WORKAROUND
To work around this issue if you are running Windows Media Player on a Microsoft Windows XP-based computer, either turn off video acceleration or turn off the video mixing renderer. To do this, follow these steps:  Start Windows Media Player. On the Tools menu, click Options, and then click the Performance tab. Do one of the following:  Turn off video acceleration. To do this, move the Video acceleration slider to the None setting. Turn off the video mixing renderer. To do this, follow these steps:  Click Advanced. Under Video Acceleration, click to clear the Use video mixing renderer check box.</li> Click OK.</li></ol> </li></ul> </li> Click OK.</li></ol>
