I got Comcast to upgrade me to Infinity in December. Installed an STB for one set and a cable card in another. All good until this week when the cable card set has begun to intermittantly fail to tune channels above 200, fine on 2-200. I pulled the card and allowed to reset and did later see that I was back in business, but should I be suspicious of low signal strength or is Comcast more likely doing some tinkering? I do know that later this month or shortly we are going full digital as they have sent out notices regarding converters for those who have aold analog sets.
