I have 4 THDs in my home and all of them have pixelation issues mostly on the local HD channels (I live in northern NJ). I spoke to Tivo tech support who after we spent some time running through the diagnostics screens, says the issue is that the cable cards are not "paired" to the units. We determined thsi since the host validation on the cabel card conditional access screend says "unknown 00". They then directed me to talk to Verizon to ge the cable cards paired correctly. I then spoke to the Verizon tech guys and they say that the "pairing" of the cards happens automatically since there is no screen they have that pairs the cards together. I went thorugh each cable card with the Verizon techs, deactivated and reactivated each cable card and I still have the pixelation issue. Does anyone know how Verizon should be "pairing" the cable cards properly?
