In Microsoft Windows Media Player 11, you transfer media to a portable device. For example, you transfer music files. When you cancel the transfer process, Windows Media Player 11 stops responding (hangs).

This problem occurs when the device uses the Media Transfer Protocol (MTP).

You try to synchronize content from Microsoft Windows Media Player 11 to a Microsoft Windows Mobile 5-based device with AKU 2.3 or a later AKU. When you do this, the phone connects. However, only the internal storage on the phone is available in Windows Media Player as a synchronization target.

You may experience one or more of the following symptoms when you use Microsoft Windows Media Player 11.

Symptom 1
Consider the following scenario. You are using an application that is registered to receive clipboard viewer messages. The application receives clipboard viewer messages by using the WM_CHANGECBCHAIN notification through the WindowProc function. In this scenario, if Windows Media Player is running, the application does not receive clipboard viewer messages. When you close Windows Media Player, the application still does not receive clipboard viewer messages.

Symptom 2
Windows Media Player 11 does not share .dvr-ms files. When you use the Media Sharing feature in Windows Media Player, .dvr-ms files that you recorded by using Windows Media Center are not shared to digital media receiver (DMR) devices.

You insert a DVD disk to watch a movie on a Windows Vista-based portable computer. You use Windows Media Player (Wmplayer.exe) or an application in Windows Media Center (Ehshell.exe) to watch the movie. However, the overall volume seems to be too low.

However, DVD playback volume is still not loud enough.

Consider the following scenario:
