A) get set-top boxen from Comcast _and_ pay more for them plus the upgrade to digital service (beaucoup more!), B) maybe get the "missing" channels back by purchasing: 1) one or more Hauppauge HVR-2250 cards to add to or replace my pair of PVR-500s, 2) one or more HDHRs, 3) one or more HDPVRs C) something else? TIA for your help. Craig.
