So I bought a Tivo and picked up a cable card from my local comcast office today. I have an any-room dvr and 1 hd box connected to it. My dvr is free, and I'm paying $9.95/mo for the other box. (the additional outlet service) I added the cable card to my account, and thought that the first cable card was free, but I was told that I would be charged the $9.95/mo. for the cable card. Does this sound right?
