New to board here. I have a bevy of D equipment ( couple of Hughes boxes, RCA D Tivo boxes, H10 & H20). I have been with D for about 10 years and love it. I had my 5 LNB and H20 installed a month ago. I'm having a horrible problem with the audio on the HD locals. I called Tech Support and they were unable to help, techs have been out twice and cannot seem to find anything wrong, D even switched out the box. Anyone else have a similiar problem?
