LINKINPARK.COM -- How Did They Do it?

I am trying to figure this out for a client that is REALLY wetting their pants to replicate the small video / giant video effect of the front page of the Linkin Park website.

Looking at the browser activity window, it shows that a single flv is downloading – however, it seems to play without buffering, so I’m guessing a flash streaming server is in play? I don’t know.

does ANYONE know how this is done? Please share!!
