Thanks Carl,

I set them all to auto and pointed the MSR+ at the centre speaker which did indeed display 'Con'.

My question to Rick was is it OK for the vMSR to be linked to the processor which is not the controller? I don't think I have more than one controller in the system. Despite the instructions for the vMSR it seems to work connected to a product that is not the controller.
