Okay it seems to be set up properly now. Rather than creating a special tag, I'm using the built in media tag. It is easier since you can copy the entire url from your browser. [media]http://www.facebook.com/v/372888365576[/media]
Inside of the Media tag you can also enter add photo sets for Flickr, as well as Google Video, Myspace video, and Youtube, using the same format of entering the full url inside the media tag.
