I'm having an issue where one of my X1 companion boxes keeps resetting itself (overnight) to 480i output on my HDTV. It's connected to a 720p HDTV via HDMI and I set the the output manually each day. Funny thing is when I set it back to 16:9 720p (or 1080i/p) the screen comes up in 4:3 format until I restart the box. Once that's done it's fine until the next day when it's back to 480i again. Any ideas??
