There is another URI mechanism contemplated for pointing at shows and 
other resources and events in the receiver.

There is a fatal problem with either of the syntaxes that you propose 
below in that the show is then implicitly bound to a particular 
service.  This is often not the case in practice, and the show may 
air on any of several services.

I'll let Dan answer his intent for tv:, but such use is problematic.

	Mike
