Thanks for the information.
My image tests are missing the plugin VFD-Icons so I copy from your image, but still no go and I have no channel names on the VFD, this needs some sort of running service? Something that need to start on boot?

Regarding the remote keys I also copy your keymap.xml but also no improvements, any menu that uses key numbers to input like an IP address doesn't work. All the rest like navigation on the menus, pressing ok, color bottoms for the special menus, etc. are working.
