I need to know which Tivo Roamio models are compatible with Time Warner Cable (Los Angeles/Beverly Hills area)? I purchased a TiVo Roamio Pro yesterday and spent hours unsuccessfully trying to get my tuning adapter and multi-stream cable card working properly with the new unit, but I was unsuccessful in the end (even with well over an hour of telephone tech support with a Time Warner support representative). I thought maybe there was an upgraded cable card or tuning adapter that I could pickup from my local Time Warner store that would make everything function properly (as my existing card/adapter was at least 2 years old). The store rep I spoke with confirmed that my cable card and tuning adapter were the most recent models, but also said that Time Warner doesn't offer any cable cards or tuning adapters that support 6 tuners. Is that correct? This led me to believe that only the $199 entry-level Roamio with 4 tuners is compatible. Is that correct? I believe others on these forums have had luck with the Roamio Plus/Pro with Time Warner, so I wanted to double-check before I return my Roamio Pro and pickup the base model Roamio instead. I do like the built-in stream functionality and larger hard drive space of the plus/pro models... Is there some way to disable 2 of the tuners of the Roamio I have if that's whats needed? Any suggestions would be greatly appreciated... Thanks!
