I have had an issue I have not seen here before. My Roamio just decided it wouldn't accept remote commands. I use a Harmony and thought it might be that so I dug up the OEM remote and it still wouldn't accept a command. None. I think I pushed all of the buttons. After a reboot everything went back to normal and has worked fine for the last day or so. Is this common? This is my first Tivo so I am not sure if this happens a lot.
