But getting it started is a fiddle. Simply switching on the PVR, DA and
kitchen TV results in no signal. You have to also switch on the main TV,
select the PVR then de-select it. Only then does the signal appear at the
kitchen TV. After that you can select or de-select anything on either TV
but get back to the PVR feed instantly.

It's almost as if the main TV has exclusive rights to the box and has to
be told to give them up. ;-)

It could well be down to the control channel aspects of HDMI, in particular that related to the HDCP copy protection mechanism.

Whilst intended for the protection of encrypted content it could well be that your PVR insists on a successful handshake to occur regardless of what it is outputting. If your setup is for some reason not allowing the kitchen TV to interact in this way then this might be why it is reliant on main TV to get things going.

Have you tried connecting the kitchen TV directly to the splitter i.e. removing the CAT6 extension?
