Close the door, I'm dressing!
Robert - will be interested to hear if it passes Dolby Digital along to the decoder (well, thats an obvious no if those are RCAs and S-video outputs)
I hope those are secondary inputs, I am still "semi"patiently waiting for the DirecTV->Media Center world.
I believe they're secondary outputs. The primary output (the computer) gets Dolby Digital, where available.
