Not fancy trying the MCE route, see how you get on with it? 
we did discuss it last night actually..
figured it would cost a fair bit more (would have to be as near silent as possible) and poss not quite as user friendly. Like the flexability and full streaming cabability along with the xbox extender to the bedroom. Would also prob take longer to get up and running.
On the offchance you are passing, I have one here that I'm not currently using. Not a great spec (3.2Ghz P4, 2G, 1 freeview tuner), but you are welcome to borrow - though I think it only has vga and hdmi out.... ....that said, it may be ati, so powerstrip and a lead *may* drive a crt....
cheers, be interesting to have a play, should our paths cross...
or maybe if you still have it available come newent....assuming I get the sky up and running.
Once sky is fixed, I can spend time getting the right solution for next time.
have got hdmi tv elsewhere, so could use that for trial purposes
