I haven't tried using a slave backend recently but remember that you can 
use a channel 'source' from the master. So if you haven't deleted your 
sources on master it should still work.

As an aside v32 supports SAT/IP. A Sat>IP tuner can be configured in the 
same way as a PCIe card based DVB tuner and has the same capabilities, 
such as scanning for channels, multirec and receiving EIT program guide 
information when that is present.  So any box that can run minisatip 
(https://github.com/catalinii/minisatip/blob/master/README.md) can be 
used as a networked interface to mythtv. I am currently running 2 DVB/S2 
tuners on a Pi4 feeding a master mythtv on a NUC with no issues.
