Has anyone see this before? I have a Roamio Plus with a SA CableCard and when I try to use tuners 5 and 6 all but the in the clear channels say not authorized and to call Comcast. Does Comcast have to do something on their end to get my 5th and 6th tuners authorized? I tested this by recording 4 shows and used the 5th tuner to navigate channels. Then used the 5th tuner on an in the clear channel and used the 6th channel to navigate channels.
