I agree, I currently have a DVR from Time Warner to supplement my HTPC. There are hardware solutions (Hauppage makes one I believe) that bundle with an HTPC to allow it to function as a DVR but they all have bugs/limitations. The biggest issue being that even with a cablecard you might not be able to get all of the channels that you would using the TW box.
But the OP is not looking for DVR functionality since they want to “cut the cord”. If you don’t need DVR an HTPC is a great solution IMO.
