Thankd for the clarification.

Wouldn;t I want 350's on all the machines I'm going to watch TV on, since
they do the decoding, and the 350 has hardware decoding? 

Can I do picture in picture? If so, then do I need two TV cards in the
frontend machine?

Or is software decoding really fast enough? What are the network
throughputs i need per "watching" location? What's the loading on the
backend machien for sending to a fronteand?
