The question is in the subject, but here it goes again. Can a Mini running Hydra connect to a Roamio running regular Tivo? A while back I bought a used Roamio that had Hydra. I tried to use it for a brief period of time, but was, in short, horrified. I rolled it back, and everything was great. I would like to try to get used to it, but I don't want to put recordings at risk. Can I try it on my mini, and get to experience (most of) it, without putting my recordings at risk?
