I tried setting up my Roamio Plus tonight. Called Tivo activated it and called my cable company (Time Warner) to activate the cable card. I was told everything is fine. It's been stuck on acquiring channels for about 2 hours. I called Time Warner back and talked to another rep that says I should have gotten a Tuning adapter and that is why it is stuck at acquiring channels at 50%. Is there anything else I should know before going after the Tuning Adapter?
