I was not sure the best place to post this, but I thought I would start here. Currently I have a Roamio that I use with 4 minis (I have a 5th mini that I have not used yet). They are connected via MOCA, and Fios is my provider using a Cable Card. In addition to watching live TV, I use watch Prime and Netflix through the Tivo system. The Roamio is 5+ years old, so it may be getting near the end of its life, and I would like greater storage capacity anyway, so I am thinking about upgrading. What should I be considering? Bolt? Edge? I hope to keep the new box for another 5+ years. All advice appreciated!
