I had a hr24 at my lake house and decided i didn't need a dvr there and I took another receiver from house and swapped out...THE HD receiver at lake house is working fine, but I can't get the DVR to work here at my house. I keep getting the 775 code. I checked SWM inverter, but it keeps saying can't find swm or swm isn't recognized. I changed zip code back...was hoping this would be easy Any help would be greatly appreciated. I have a Slimline 5 dish??
