Have you tried a full cold restart of the one with the problem? It sounds like an issue specific to that device. — A member replied: “Thanks for the amazingly quick response!!! I did unplug the errant DVR and waited 45 seconds before plugging it back in. I then waited the requisite 10 minutes while it went through the entire reboot process.”
