Roamio Plus, Charter Cable. Cisco cablecard is my third try. None of the previous Scientific Atlantic cards would automatically update the firmware to PKEY18.104.22.16801 as they are supposed to. Tivo said to try a different cablecard. I'm on the third try and it won't update. The current card has firmware that ends in 2401; all the previous one ended in 1601. Tivo says they can't force an update. Charter is clueless, they say they can't update the firmware -- they actually advised me to try Weaknees! Good idea, but the next Charter technician said it would void something. Any ideas on how to get the card to update firmware? I was missing 3 of 4 tuners before (Tivo advised me to restrict to 4 tuners for now). Now it's only missing Tuner 0.
