I installed today a Quad Polar Legacy 4 O/P LNB.

When I went to view channels nothing was available although channels were listed and the dish moved from satellite to satellite. I did a rescan and the channels came back. But for some odd reason they come in duplicate. This happens with both my Edison receiver and Koqit receiver. This is strange.

At first I was thinking that I was getting SD & HD versions of the same channel but this isn't the case.

Has anyone seen this beofre? What's this called? Can it be fixed?

Thanks!
