The lone channel in the 4 networks I get in hd from Dish that is constantly having problems is the ABC station. I can not tell if this is a ota problem as well becuase I "moved" to Houston . I have sent many many many emails to the dishquality folks and they say be patient it is new technology etc etc. They tweak it and for a while it works fine but then it goes right back to sh*t. The Fox hd station in Houston which is 720p looks fine with NO breakups at all, so I don't understand why the ABC station in 720p looks like this. When they first turned them on last May the ABC station looked fine but it is now constantly breaking up and green screening and audio warbling to the point that I have now switched all my recordings to the ota ABC station in Beaumont which doesnot have hd yet. The picture is constant and no break ups but it is in 480i .
