Target application: RTLKlub spider

My wife wants to watch Hungarian TV clips, and RTL has some stuff online - but it takes 5.5 minutes to get a 2-minute clip out through the Hungarian pipe. Obviously, I need to cache things, and so: a spider. A task!

I know how to cache movies given Flash players, but some of that stuff is in Silverlight, so I don't know whether I can do that or not. But at least I could get the Flash movies.
