Satellites.xml is pretty useless here because some of our satellite transponders change a lot.
During syncWithKnownTransponders, The Nino is taking fec and other wrong values from similar transponder(s) in the .xml file and applying them to what it scanned. It seems to be all cosmetic and does not hurt reception of channels. But it can be confusing.
The skin infobar usually shows the correct FEC for the channel regardless of what the blindscan logged, but the bogus FEC will show in positioner setup and in other places.
Then you also have the Nino Pro assigning bad DVB-S fec's on its own - without any transponders being in satellites.xml for the satellite, and without the aid of syncWithKnownTransponders.
So there are two little issues, both cosmetic.
