After reading about all of the troubles people have had about getting a cablecard to work, including my own two hour ordeal with my first Tivo HD, I thought I would brag on Charter for a 10 minute cablecard install for my newest HD. The installer showed up on time with 1 M card and 2 S cards, put in the M card first, the cablecard screen popped up, he called the office with the info and voila everything worked. He stayed long enough to be sure that all of the channels came in and that was it, total time 10 minutes. This is how a cablecard install should be. The only downside was that I had to pay $35 for a truck roll instead of letting me plug the card in and call in the data.
