After a week of TWC technicians, support calls, searching through this and other sites I still don't have anything close to reliable service using my new Roamio. I've obediently exchanged M-Cards and tuning adapters with absolutely no luck. I still lose most, if not all, channels several times a day. I simply need to read that somebody... anybody... is successfully using a Roamio with TWC. If so, I'll continue to plod forward. Otherwise, I'm done with all this self-inflicted pain.
