Can somebody tell me what transponder and satellite WCBS New York and WNBC New York are on? I have been having an awful time with the CBS channel for the last week to ten days and now the NBC station has been acting up. I get bad pixelation problems and then I get the 771 error message. I have unplugged and reset this receiver so many times over the last week and a half I've lost count. I would appreciate any help.
