Advertisements If I have one suggestion for those just getting the CableCard install. DON'T LET THE INSTALLER LEAVE When they came over, they installed the cards, called the numbers in and wanted me to sign the work order. I refused until I did a successful channel lineup on both cards. They weren't happy. But, then again, I tipped them $10.00. It's a lot cheaper than the mental anguish of having to call and get them to roll again.
