I am also in Howard County. Not to scare you, but my experience has been two missed appointments (without them notifying me), then last night, the tech showed up 1.5 hours AFTER the window, then left without anything working (assuring me that it would work "in a couple of hours"). Needless to say, I still have no working cableCARDs. Good luck to you. My question is... if my SA cableCARD says "multi stream," I shouldn't need two, should I?
