I'm having the same problem, and Comcast will be here shortly. How do a I tell them to validate the cards. I've spent numerous hours on the phone, and no one there seems to know what to do. My Conditional Access info is as follows: Card 1: Encryption: DES, Connected:yes, EnabledByCP:yes, Auth: Subscribed, , CA Enable: Possible, Host Validation: Unknown 00, Copy Protection Key: Disabled Card 2: State: Subscribed. (doesn't list the other info listed above for CC1). Host Validation: Unknown 00, Copy Protection Key: Disabled. Thanks.
