HDMI Spitter doesn’t work with new Sky Box, so cant output signal to second TV in another room!
Worked fine with My Sky HD Box
It is likely that will be the new Sky Box enforcing HDCP. Old Sky boxes did not enforce it - if the TV or splitter did not respond to HDCP, they just turned it off. So it is likely that you need a splitter that will do HDCP on its input but not on its outputs, as it is not possible as far as I know to do HDCP to two different output devices at the same time.
