[mythtv-users] Mythtv backend setup filter issue?

[Don Brett]

I have Mythtv (V-30.0) on Ubuntu-Mate, 18.04, with one HD-PVR (cable TV) 
and one HD  homerun Quatro (antenna).  Mythtv-backend-setup channel 
editor shows the channel lineup for each video source. Filtering for the 
HD-PVR (cable TV), it looks fine.  Filtering for HD  homerun Quatro 
(antenna), it show both listings (cable TV and antenna).

I can delete the cable TV channels from the antenna listings, exit and 
re-enter Mythtv backend setup (without starting the backend or running 
Mythfilldatabase) and the deleted channels stay deleted. Returning to 
normal use, sometime during the next day, the deleted entries come 
back.  Is it a setup filter issue, or is something putting the channels 
back in?  Maybe when it runs mythfilldatabase?
