I am gradually giving up on the idea of being able to record HD off a  
DCT6200 box via firewire... As a tradeoff I was thinking of feeding  
the video into my PVR150 card via S-Video, but the question is how do  
I switch the channels then? Firewire switches channel no problem, but  
how do I tell Mythtv to record video via one cad and switch channels  
for the recording with the other (FW)?
