So this is weird. I have the H20 100 and have recieved all the new HD channels. All look great. However on channels: CNNHD FUEL HD FX HD Speed HD Toon HD There is no sound. It pops in sometimes like I'm getting a bad signal, but the picture is always perfect. All the other HD channels have perfect sound. I had a Direct TV tech come out for about 5 minutes to tell me he has no idea. Not sure if anyone else is getting this, but DTV says there is nothing they can do...which is odd.
