I've been seeing pixelation and audio dropouts on satellite HD channels for about a week now. Last night, I proved the problem is tied to a tuner, but I still am not sure which tuner or how to fix it. Here's what I did. While watching one HD channel, I noticed the problems had come back again. I switched to another HD channel, and that channel was fine. I ran the signal strength tests in setup and changed tuners on 110 during the tests. I assume this somehow toggled which tuner was selected first, because when I went back to the program I was watching, it had cleared up, but when I switched to the pervious channel the other channel was now having the problems. I was able to repeat these results over and over, pushing the problems to any HD channel I chose. So, am I right in thinking that I forced a tuner change? Is it a tuner issue or a BBC issue? I am not getting any local stations in HD over the satellite, so can BBC's be removed, or do they serve other functions as well?
