Thanks Gents! I will try the TCP control setting (SHould be on or off?!)

As for the IR, I have two little logitech harmony IR extenders, that plug into the hub, inside my cabinet. All the equip except the TV is inside a salamander type cab.

One extender sits near the front of the Anthem which is on the right. The other is near the back of the TV which is on top of the cabinet. And the Hamony hub is inside the left part of the cabinet near the cable box. So all 3 areas should be getting strong IR. ALthough

As I understand it my logitech remote talks to the hub non-infrared - ie there's no need for line of site.
