Happy New Year all. I have a four input HDMI switch from Amazon. It arrived today and I get a picture from the mazon Fire TV box, but nothing from either T2 HRD or the Foxsat HDR. It has a PIP feature and I see what the Humax's are tuned to, but if I select them I get sound but no video. I've included a shot of the leaflet that came with it, in case there is a compatibility issue.
