I have this problem every year for the last two years. The NFL Redzone on the Joey in one of my bedrooms pixelates like there is a signal problem with the channel. However, the Hopper that it is connected to plays the channel just fine without issues and and so does the HWS in another room. It doesn't even matter if I join in progress with this Joey it still does it. To make the situation even more weird this is the only HD channel that has this issue, every other HD channel on this Joey plays fine without issue. It's just always the NFL Redzone HD channel. The only thing I can think of is that the wiring has become compromised between the node and the joey, but you would think other channels would have this issue.
Hardware: Hopper-2000 over three years, Joey over three years, HWS less than a year old.
