For the last couple of months the volume on DirecTV is so low on most of the channels even turning it up as far as it will go makes it barely audible. On some of the channels the volume simply is not sufficient to be able to hear. Someone told me it's because I don't have a HDTV. Apparently the volume is calibrated for HD TV's which makes it too low for "normal" TV's. Does this make sense and is DirecTV working on a "fix" for the problem" or do we who don't have HD TV's not watch our favorite channels?
