I have a Premiere (2 tuner) and a (new) Roamio (4 tuner) that are both connected to Time Warner Cable via Cisco Tuning Adaptors. Both are working, displaying all the digital HD content and Premium content (Showtime) that I subscribe to from TWC. However, when I attempt to use the signal strength meter option on either the Premiere or the Roamio, I get a message saying there are no digital channels.
Specifically, I go to the Tivo Channels Settings menu, and select "Signal Strength - Cable". I am presented with a message stating: " Signal Strength is unavailable because your cable channel lineup has no digital channels." That's odd since the digital channels are all viewable?
Next, I navigated to the Tivo "Remote, CableCard, & Devices" menu option and selected "Cable Card Decoder". It shows "M Card Inserted" and then if I select "Test Channels", I am presented with a reply stating "No Channels Available."
I know for a fact that in the past, my Premier unit would display the signal strength for all my channels correctly. I haven't used that test feature recently, so not sure when it may have stopped working. When I got my new Roamio last month, and attempted to test signal strength on it, and failed as described above, I looked at the Premier and saw the same results (i.e., no digital channels and no channels available).
Since I can indeed see all my digital channels on both the Premier and the Roamio, why am I getting the erroneous messages on the "Test Channels" and "Signal Strength" tests? I'm perplexed! Thanks in advance!
