Channel 9 is a video service run by Microsoft. Channel 9 provides a way to embed videos 
but is not yet on the WordPress embeds core list. This plugin allows you to simply paste 
a URL to a Channel 9 video as you would with any other embed service into your post. 
The video from Channel 9 will show at that location.
Channel 9 can be found at http://channel9.msdn.com
