I have a Roamio Pro currently running software version 20.7.4.RC2-840-6-840. I had the Power Savings Settings on "Low". Today my wife complained that our TiVo Mini in the kitchen was not connecting to live TV, it basically timed out and showed "The connection with the box has been lost" message when trying to watch live TV. Interestingly, it had no problem streaming already recorded programs. When I went downstairs to the Roamio Pro, it was in sleep mode. I pressed the "TiVo" button on the remote to wake it up, it displayed the "Waking up" message - and it never proceeded from that point. ("Never" meaning nothing happened after a 2-3 minute wait.) So, I had to pull the power plug to reset the thing. This isn't the first time this has happened, but it happened so infrequently (maybe 3-4 times total during the past 2 years), I didn't pay much attention to it. I don't know if this happened to anybody else. It smells like a software problem to me, not a hardware one. Anyway, I'm just writing this down here for the record. For now I changed the Power Savings to "Manual" (which is basically "off").
