I was watching a recording when I heard a little "pop" and the picture froze. I could do nothing with it and could not turn TV off with remote; there was absolutely no communication between remote and DVR. I could access Netflix, Hulu, etc., and turn TV on/off with the Vizio Remote. I finally unplugged DVR for 30 secs. I can now use Uverse Remote to manage recordings, guide, menu, etc., but still have to use Vizio Remote to turn TV on/off and manage the volume; weird! ANYONE???
