I may be using the term Pixelation wrong: the screen shows occasional bursts of rectangular areas of multicolored noise. The problem initially manifested in our recordings on DirecTV of So You Think You Can Dance--extremely distracting. Tech support suggested replacing the Genie, but we did not because of the large number of recorded programs we would lose. And inertia. We are now transitioning to the Bolt OTA and notice the same, albeit less severe problem in viewing the recordings. On viewing live shows in the morning (SYTYCD is recorded in the evening), there is minimal pixelation on the Bolt, and less so on DTV. Recordings of other programs either on DTV or Bolt do not manifest the same pixelation.We use our former rooftop antenna mounted in the attic of our 2 story house which gives us an antenna strength of 75% on Fox; I do not know how to view SNR on the Bolt. Antenna web recommends a small multidirectional antenna. While there are barrel connectors in the coax feed, I have removed all splitters. None of the other channels with similar signal strengths give similar problems. While I could alter the antenna, I am curious about the relative isolation of the problem to Fox on 2 dissimilar systems. TIA for any help.
