I've got a Roamio Plus (perhaps a year old) that just spontaneously rebooted this evening while I was watching a currently recording program (perhaps 15 minutes behind live TV). I also have a Roamio Pro (only a few months old) that has spontaneously rebooted recently. Both are running software 20.4.5c. I don't see any recent threads about software updates so I assume I have the the newest. It's hard for me to believe that I have two units with hardware problems. So is it just software? Anyone else having reboot problems? I don't see a recent active discussion about this.
