  1. Go to Tools > Internet Options
  2. Click on the Security Tab
  3. At the bottom, uncheck the box labeled Enable Protected Mode
  4. Restart Internet Explorer


Troubleshooting Windows playback: Media Player settings
If you are unable to view Mediasite presentations, try adjusting the settings below.

Close your web browser and launch Windows Media Player (this is usually available under the ALL Programs option on the Windows Start menu). In Windows Media Player, go to Tools > Options; in newer versions of Windows Media Player you may have to right click next to the Now Playing button in order to access the Tools menu.


  1. On the Player tab, check the Connect to the Internet box
  2. On the Network tab, check the RTSP/UDP, RTSP/TCP, and HTTP boxes, and configure the streaming proxy settings if applicable
  3. On the Performance tab, select Choose connection speed and the appropriate connection speed


When I try to play video files streamed from the Internet, why do I only hear the audio?
When you receive streamed content, communication occurs between the Player and a Windows Media server regarding the connection speed of your computer. If the Player communicates an incorrect connection speed to the server, the server may try to thin the stream, which means that the stream quality decreases and the Player may lose video altogether.

You can prevent this from happening accidentally by manually specifying the connection speed. In Windows Media Player 7 or later, you can specify your connection speed, by doing the following:

  1. On the Tools menu, click Options, and then click the Performance tab
  2. In the Connection Speed area, click Choose connection speed, and then select the appropriate connection speed.
Troubleshooting Windows Playback: Internet Explorer settings

If you are using Internet Explorer as your web browser, go to Tools > Internet Options to adjust the settings below.

  1. On the Connections tab, if the Dial-up and Virtual Private Network settings box is empty, click Add.
  2. In the New Connection Wizard, choose Connect to the network via broadband, enter a name for the connection and click Finish.
  3. Back on the Connections tab, highlight the new connection you made and choose Never dial a connection, then click OK.
