I have eastern arc setup with a side sat that I recently moved to 129. No outside switches involved. It sometimes picks 129 and sometimes 61.5 , no rhyme or reason. I had the side sat on the 110 sat and I didn't see any problems on the setup . So maybe I need to drop the side sat entirely. I could just replug it to 110 once they move all the hd to 72.7 and eliminate the 61.5 sat entirely, by covering in foil. That way the 110 would cover the Houston locals for me instead of 61.5. They come in stronger on the 110 sat anyway.
