I had my 6000u that I got for $149 installed today and I was moving my other 6000 to the bedroom for a HDTV I will buy early next year. Ran into some problems and the installer couldn't figure out what was wrong but plans to comeback with another installer and more equipment. The problem is none of my HDTV package channel(DHD,HD Net, HD Net Movies,EspnHD) will tune in and transpoder 17 has almost no signal strength. If you change the transponder number you get a good signal strength but still no picture. Any ideas what this could be?
