This is an error that appears in the log when I attempt to start MythTV frontend.

I cannot remember ever seeing this before.
Is it fatal?

How can I avoid it?

TIA

At a guess, MythTV has a CEC Handler, and it "listens" for
messages from other devices on the "bus".

To give a practical example of what CEC does:

BluRay -------- HDMI ----------- TV set
Player

Now, when you use the TV remote and "turn off" the TV set,
the TV set sends a CEC message to the BluRay player.
The BluRay player, in sympathy, turns off at the same time.
With some lucky wiring, your entire AV Rack could go Off
at the same time.

Potentially, you could have a MythTV computer and a TV
connected like that. You use the remote on the TV and
turn off the display. The CEC would send a signal to the
"CEC Handler", and the CEC Handler would then shut down
or sleep the computer. As if the soft Power button had
been pressed sort of thing.

If some part of the hardware path doesn't present a
viable CEC, then you'd likely get a (non-fatal) notification.
Don't lose any sleep over this.

You could attempt to find a Preference that controls this,
and turn the feature off.

Thank you. Now I have to chase up the remaining errors. :(
