PVR.WMC not conecting with ServerWMC

At least that is what I think is (not) happening. I have installed ServerWMC and enabled the PVR WMC client, allowing firewall access and directories shared to everyone, but when I start Kodi the window at top reports scanning for PVR services then times out with a message that the PVR manager has been enabled without any enabled PVR add-on. Kodi then opens the add-on page, I enable the PVR WMC client, then return to the TV page and disable then re-enable TV under the general tab and Kodi then starts scanning for PVR services again, and again times out.

Something I am doing wrong obviously, but what? All help appreciated.

TIA
