I use a pretty similar set up with no problems (Using a GF5200).
I just bought a cheap Digital TV card (Compro DVB-T200) and installed Media Portal.
It works a treat.
[edit]
Bugger...Just noticed the cable thing...and Elf beat me to the Media portal recommendation...It is really rather good though.
Oh...and I got an OEM MCE remote kit for about £15-20 to control it all!
