It is sitting on the entertainment center. Our house is a pier and beam house. When the kids coming running in the living room the rumbling in the floor causes the 722 to go to the aquiring signal screen for a few seconds and then back to normal. I can have my foot on the foot rest on the couch. I can bring my foot down to the floor and make this same thing happen. I can't even really touch the box or move it a little without this happening. Is this a flaw that I need to call E* about? I have had a hand full of dvr's and this is the 1st one that has done this.
