Alrighty, it's not as easy as embedding Youtube, but when you bring up the "embed" option from the menu, you can get the location and use the [flash] tag to embed the video.
For example In the embed window is all this code:
<object width="512" height="296"><param name="movie" value="http://www.hulu.com/embed/oWWRdI-BR-pLkc3qxBiFvA/0"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.hulu.com/embed/oWWRdI-BR-pLkc3qxBiFvA/0" type="application/x-shockwave-flash" allowFullScreen="true" width="512" height="296"></embed></object> All we care about is the URLs in there.
So we could do
[flash=510,280]http://www.hulu.com/embed/oWWRdI-BR-pLkc3qxBiFvA/0[/flash] And that would produce this
