Did you read what Matrix10 wrote? When you select a channel on satellite, Diseqc selects that one, which you are watching. And THERE IS NO WAY to give a signal to your box from other in your actual configuration.diseqc it is on all satelit 1.1 and all satelit works perfect ,only problem is when is PiP on.
