Do you want to banter or discuss?
Fine with me. I brought up MacroVision because a lot of these things have it and I encounter folk with stories like yours.
If you want to banter, just say so. I think the fix is to go back to what worked.
-> If you feel it's cable noise then fix that and you're done.
I do not know of ANY system that gets around MacroVision issues. I mention it so you can research that.
However once in a while you encounter someone that declares that's not it and you have to give them more time to think it over.
