I have four DirecTV receivers and each one has a different number of All Channels and Channels I Get. My HR44/500 says All Channels are 795 and Channels I Get are 774; HR24/500 says 907 and 834; H23/600 says 679 and 658; HR22/100 says 805 and 784. I created a comparison table by receiver by satellite by transponder and they are essentially the same ... the HR24 gets satellites 110 and 119 where as the others don't, otherwise they all get the same satellites and transponders. This difference was initially noted on the H23/600 when it would not display the Playboy HD channels. If I turn Hide SD Duplicates OFF it will display BOTH SD & HD Playboy channels sometimes! When I Hide SD Duplicates it turns off the HD channels and leaves the SD channels. Attached is a PDF of my comparison table. Any other suggestions before I call DirecTV tech support and spend and hour trying to explain this problem?
