I did as you suggested (set WakeUpThreshold to 300), and after
restarting the backend to make sure that it has seen the updated
parameter the result is as follows:

Feb  5 20:24:50 mythtv[2529215]:

So I am indeed getting recording pending events before the recording
starts. It would be good if they came earlier still (my STB needs around
90s from power-on to start accepting infrared commands so that I can
change channels), but we're getting closer.

I can of course live with the recording pending event that still fires
after the recording has started, with a nonsensical negative value.

Yes, thank you very much for your help.

Cheers, Jan
