OK, here is the deal. I got a new Roamio Pro last week, because I wanted the 6 tuners (among the other things offered). Got an M-Card (Motorola) from COX Cable in Hampton Roads. I fire the baby up, call COX Cable and get the tuner adapter married to the M-Card, and all is well. I got all of my channels just fine. Next, I tried to test record some shows. After getting the TIVO to record the second show, now I get this error on ALL of the other channels: "This channel is temporarily unavailable. Press Select to try tuning to the channel again. Contact your cable provider for more information". No amount of Selecting got those channels back, but a reboot of the TIVO fixes it. So I chatted online with the TIVO support. After about 90 minutes, we determined that the (outdated) M-Card had older firmware and only supported 2 'streams' and that I should get another, more updated M-Card. I did some homework first, searching the forums here, and I temporarily reduced my tuners to three (the third tuner still knocks out all of the other channels, though. I don't know how to get the Roamio down temporarily to two tuners). Today I went to two different COX Solution Stores to ask for an updated M-Card that would handle 6 tuners. Both store personnel said they had none, and didn't even know if was possible to update the M-Card firmware, or when any updated M-Cards will ever be in. That was understandable, as the TIVO Roamio is new to them. HOWEVER, in the corner of each store was THEIR DVR box, supporting 6 tuners. It was run by a Cisco M-Card, which I think would work in the Roamio Pro. But they refused to let me have one of those M-Cards. So I am stuck with a disabled Roamio Pro, little better than my Tivo Premier. My question to the forum is this: Is there any other way to get a correctly updated M-Card other than through the cable provider? Or am I stuck to a new M-Card arrives in town, whenever?
