TV 1 in our family room is showing on a 15+ year old Pioneer big screen. TV 2 is upstairs on fairly new Toshiba LCD. The picture on TV 2 is just fine but TV 1 is periodically going "wavy", e.g., a person in dark clothing or dark lettering against a light background looks like a serrated knife blade. This only happens while watching live, not during DVR playback and mostly during commercials. So, I'm wondering if it's possible for one tuner of a 522 to go bad or is the old ginormous Pioneer (50" rear projection cabinet) finally dying so that we will be able to get our family room into this century? FWIW, the 522 is over 5 years old.
