This morning I woke up to my T60 saying that all channels are unavailable. I checked signal strength. All were good. So I rebooted it. Everything is back. I checked the Recording History and discovered that shows to record at 10pm and later didn't because of Internal Error 4. This is only the second or third time this has happened with this unit in almost 5 years. So this prompted me to start this thread about the small annoyances that can be fixed with a reboot. I'll mention one more and then let others chime in. - The recording light is still on even though it isn't recording. The show is in the NPL with a red ball.
