Comcast CSRs don't know that HD tvs come with tuners and can't speak with you unless you have a BOX. It is standard Comcast policy to install an SD box to your HD tv, the 1st box is usually free. A standard HD box is $10 a month, with an $8.95 monthly advanced service fee, so $18.95 a month for the 1st HD box. As of my last conversation with them they don't charge extra for color!
I stay at a condominium that has a Comcast master account for all units. Tenants are theoretically guaranteed a free small slate of channels. Yesterday I noticed that two local network channels weren't coming in, so I rescanned and all's good again. But that is annoying to have to do, and I suspect a lot of folks don't know they can re-scan and regain the channels; they think they have to rent a box from CC. What's this practice of sabotaging the setups of innocent folks called? Is it even legal to switch things around?
