Cablevision is aware of the firmware issue with their Cisco/SA cablecards. The Roamio compatibility issue seems to have caught them by surprise, but they were on top of it almost immediately. Cablevision says they are testing the updated firmware necessary for proper functioning of the Tivo Roamio 6-tuner boxes and, if all goes well, they will push out the update as early as this week (per an email to me from Wilt Hildenbrand at Cablevision). BTW, I have a basic Roamio and a Roamio Pro, both of which seem to be operating OK on the outdated Cisco/SA 1601 firmware (even when I tune to encrypted channels on all 6 tuners on the Pro). If the problem is imtermittent, maybe it just has not shown up yet.
