Thank you for your reply. Yes, I understand sdt - 1 ( i.e.ERROR) is a result of a certain condition( a query).Do you query tuner chip or what do you query that you receive that error result?
I have 3 LNBs and 1 DiSeqC, no multiswitch. I can use that installation successfully with another satellite receiver. Only this one does not work - see the log ( my first post) when searching a transponder.
