I have “Digital Preferred” Cable service. I have one Hi-Def Set Top Box and three regular ones. I have no problems with the Hi-Def Box and two of the three regular Boxes. However I can not get all of the "Digital Preferred" channels on the TV with the remaining Regular Set Top Box. When tuning to some channels I am getting a message that says “NOT AUTHORIZED” or “SUBSCRIPTION SERVICE”. I printed out the List of channels that I am supposed to get with the Digital Preferred package and here is a list of the channels that I am not getting on one of my TV’s. The other three get all of the channels just fine.
