Noticed some of my channels were coming in pixelated. Not on any local channels just the satellite ones. Then intermittent messages appearing telling me DTV was trying to find a satellite signal. Then screen turned blank and a message showed up acquiring guide data. The screen said if nothing happened in 2 minutes try resetting the DVR. I did but it still just keeps trying to acquire guide data. Now I can't go anywhere on my TV. The only thing that works is my List, which allows me to play shows I have recorded but I can't even get my local channels now. Tried calling the 1-800 number in entering in the code 771, but the voice menu thing was no help, just keeps asking me to do things I've already tried. We are not having bad weather here, just a little windy but nothing to brag about. Any thoughts. I've already tried resetting the box several times to no avail. I should note that the standard receiver in the bedroom seems to be working fine, icluding having the guide data that my DVR cant seem to find.
