OK I have pretty much set it up to try in the morning.
There are a couple of things I need to check first.
In the Main TV device Adjust Input Settings, select Method
3 (discrete method), edit the input list to have at least
2 entries (HDMI and whatever you plan to use in the future).
When I was answering your previous post, I used the HDMI1 to select the input list and scroll thru. On setting the above bit up I could not find an AV button equivalent and I am not sure what the scroll keys would be as I seem to remember the Direction buttons did nothing.
Thanks for your efforts, I'll check it out and get back tomorrow.
