Given that the detection and correction of unwanted elements takes a few seconds, I'm keen to only use it for scheduled recordings and not for every channel change in Live TV.

Mike:

You might want to do a quick search of the archives, but IIRC sending
an "exit" button press to the STB does nothing unless there is
something to exit from.  I issue it in my channel changing script and
it seems to work fine -- though I don't use live TV.
