I know this topic has come up several times in the past, but after going through them, I don't see a real decisive answer. I have a Comcast set-top box as well as a Tivo with a cablecard. On my Comcast bill, I have a charge of $9.95 for "HD Additional Outlet". I was told by Comcast that since I have HD service on the cablecard, I am charged $9.95. Does that sound right?
