My Premioer loses signal occasionally. Seems to happen around 10:00pm when I'm trying to record BREAKING BAD! You can tell that this is a serious matter. The loss is temporary and I see no further trouble for many days. I keep a Sci. Atlanta connected to backup the TIVO which fails much more than the Sci. Atlanta. It records the show lost to the TIVO, so the problem is surely related to TIVO losing signal.
