Im not familiar with PC TV tuners and am wondering the following about Verizon FIOS and an HTPC. 1) Is there such a device that makes it possible to view and DVR all subscribed premium FIOS channels? I am aware I would need a cablecard. 2)Is there a better program than XBMC and WMC to use for a HTPC? 3) what is the typical "standard" cpu used in HTPC builds?
