As I have my sky and AV equipment in a cupboard, my set up is a coax cable from RF2 to a loft box and then caox from there to main TV with sky eye on it. I also have HDMI from sky box to that tv and all works perfectly.

I have now run a small hdmi cable from sky box to hdmi splitter and two hdmi cables to main and other tv, both work fine but the sky eye no longer works, take the splitter out and eye works again.

As the eye works on the coax I cant understand how the hdmi splitter is interfering?

Any ideas anyone?
