I think it's time to retire my six year-old TiVo HD in favor of a Roamio Plus. At the moment I have both the TiVo HD (w/ mcard) and a Verizon HD DVR in two different rooms. I'm thinking that I'll upgrade in the following way: Keep the TiVo HD and Roamio in the same room for a while, until we finish watching the old shows on the TiVo HD. Sell the HD box on ebay (it has a lifetime sub) and use the proceeds to get a Mini. Replace the Verizon HD DVR with the Mini. I wonder if any other Verizon Fios users know if I can move my existing mcard (it's about a year old) to the Roamio and then call verizon to get it paired with the new DVR. Has anyone been successful with this approach?
