Hi, I have in the past very successfully recorded to hard disc from my Tivo box, I connect via HDMI cable to a Black Magic Intensity Pro capture card through an HDMI splitter Just lately though, although I can record the picture (I can also see the sound level meters are active) I get no sound, I have tried new cables and a new splitter, also different audio settings, to no avail. My question is, could this be HDCP operating on the sound only? It is more of a puzzle considering that until a short while ago I had no problem, very frustrating. Any clarification you can give gratefully received. Mike T.
