For anyone trying to pair a cablecard, the only number to call should be the national repair line(888-824-8988). Either Rochelle X17316 or Michael X17716. My new Roamio is paired. The Comcast Activation line only were able to mess things up but Michael was able to see the problem immediately. Data ID was off, and a billing code had to be updated since the Roamio's have VOD capablility. He even told me NEVER call comcast directly for cablecard issues.
