Oh yes! I think you're right about satellites.xml (seem to remember it happening in the past with my 500s). I can watch 19.2, 13E and 30W (found and stored) but selecting 1W channels goes nowhere which would seem to support the 0.8W in the new image and 1W in the old Gemini image.
The transponders are shown if you select Transponder Edit but not in the Motor Config page for 1W and the transponder scan page doesn't show 0.8W or 1W.
Gotoxx doesn't work at all. So if the channel lsit and associated files conflict with the files in Gemini what's to do? Give up and reflash?
I knew I should have reflashed it with Gemini 3.60...
