Comment (by Klaas de Waal):

 A check with the current v32-pre software version and with a newly created
 RPI slave backend shows the following behavior when running mythtv-setup:
 - On both master and slave backends the "Video Sources" shows the same
 list of all video sources.
 - On both master and slave backends the Transport Editor can only be used
 for a video source that is connected to a capture card on that system.
 So on the slave backend one should see all video sources but only the
 transports of the video source connected to a capture card on that backend
 can be edited.

 As reported, the capture card on the slave backend can be used to do a
 channelscan. This shows that the capture card is connected to the video
 source.
 The problem is, as I understand it, that it is NOT possible to use the
 Channel Editor on that video source on the slave backend.

 There have not been that many changes in this part of the software since
 v31 and none that I can directly relate to this.

 The message in the log:
 {{{
 CardUtil: Can't open DVB frontend (/dev/dvb/adapter0/frontend0) for
 /dev/dvb/adapter0/frontend0.
                         eno: Device or resource busy (16)

 }}}
 is what you get when mythtv-setup is started while mythbackend is running.
 Please make sure that this is not the case here.

 To investigate this further, a log created as follows:
 {{{
 mythtv-setup -v general,channel,record,chanscan,database --loglevel=debug
 2>&1 | tee ms-20200623-2245.log

 }}}
 when trying to start the Channel Editor might be useful.
