So far a pretty bad experience from Comcast here. Tech was on time -- but that was the only part that worked. First set of cards installed and the tech struggled to get them to work for 1 and 1/2 hours. Never could. Second set installed and called to initialize them. Got the "good" error -- but so far (nearly 2 hours later) I only get 2 channels -- both local HD channels. The cards still show as Auth: unknown so I don't think anything is working right. I've called to get them initialized 3 times now and just don't get anywhere. Time to try yet again.
