I tried watching this video, had to update my silverlight, close down the browser, open it up again, try playing the video again but alas to no avail.

I probably should have tried drawing up a pentacle and sacrificing a chicken or something but I really don't want to go down that route.

Morale of the story - MS please up your game a bit. If Silverlight cant play your videos on your hosted sites then what hope is for other lesser mortal developers out there?
