Which is your HD Locals-into-Local satellite? No locale given so we can only guess.
If you are Western Arc then most HD locals are from 129W with a few from 110W.
The SD channels are likely from a different satellite.
What are your signal strengths? 110W 119W and 129W?
Yellow button + Diagnostics + Point Dish. Do it when not recording.
129W transponders 1 to 16 are LIL spotbeams, 17 and up are Continental (CONUS).
If Eastern Arc they could be from 61.5W or 72W with some from 77W.
The installer should have gotten this for you.
