Allows Administrators to enable and disable the Media Explorer Bar and set the auto-play default. The Media Explorer Bar plays music and video content from the Internet. If you disable the Media explorer bar users cannot display the Media Explorer Bar. The auto-play feature is also disabled. When users click on a link within Internet Explorer the content will be played by the default media client on their system. If you enable the Media Explorer Bar or do not configure it users can show and hide the Media Explorer Bar. Administrators also have the ability to turn the auto-play feature on or off. This setting only applies if the Media Explorer Bar is enabled. If checked the Media Explorer Bar will automatically display and play the media content when the user clicks on a media link. If unchecked the content will be played by the default media client on their system.
