Ask to speak with a supervisor in your local Comcast office. I too was told this by the CSRs but the supervisor confirmed that the $5/mo HD charge is equipment related. I returned my STB when they installed my 2 cable cards. The only additional charge is $1.50 for the 2nd cable card (1st is included with the digital package). He credited back the charges for the previous month and I have not been billed for it since. BTW, I live in the San Francisco Peninsula area.
