Thanks so it is just a roadblock. Please excuse me to keep going: most things either play or don’t play depending on that HDCP (yeash HD CP :s), but if I strip it away using say the second output of a splitter it will play. Is it the case that for example appleTV box will only output 720 if it doesn’t get some kind of positive handshake?

Allow me to add that every time I’ve removed it I’ve had full licensing and permissions, just that HDCP was in the way.
