There is a setting in the 'Recording Options' page of each Capture Card 
to set or unset 'Use DVB card for active EIT scan'.

It is easy to miss. I presumed that unchecking that item will set 
useonairguide to "0" for all channels in the video source matched to 
that card. But maybe not: it may well be a global setting wrt that card.

But maybe not! There is also a setting on each 'Video Source' page: 
'Perform EIT scan'.....

I'm ....... not going to even *attempt* to think about the multiple 
priorities involved in this decision tree. Someone who is feeling 
particularly masochistic can dive into the code to find out which is 
rock, paper and scissors among these choices if they are set at cross 
purposes.

The default setting for channel.useonairguide is "0". I doubt that it 
was "1" in v.0.21.
The default setting for capturecard.dvb_eitscan is "1" which may be a 
source of confusion. The setting is not particularly noticeable. And it 
*may* cause the channels in the video source matched to that card, to be 
set to "1".  No idea.

I have never used or even tried to use an EIT scan so this is just an 
informed guess. (That makes me an "expert", I believe).
