I have a RSP-1066 connected to my RMB-1055 with a Denon DVD2800 MKII dvd player and Definitive Technology 5.1 speakers. The DVD is connected using a Digital Coax cable. The problem I seem to get is sometimes when I play a DVD the processor displays a CB speaker when there is not one connected. I am unable to alter this. Is there a setting I have over looked?
