Pixelation on certain channels
Every minute or two I am getting brief pixelation and a short audio glitch. It happens on some channels and not others. From tonight, happens on: FX, HGTV, and our local NBC station. Does not happen on: ESPN or local PBS station. Been going on for a month or two. Watching via main receiver which is a Genie HR54-700. Have tried soft and hard restart as well as unplug, wait, and plug back in. No change. All connections seem solid. Ideas?
