Hi all, I just got Directv installed a few days ago. Great picture and sound, but,on a number of channels I occationally get what looks like the picture pixelating or digitizing, and the sound pops, and chirps quite loudly. Looks just like a bad DVD. Know what I mean? I have a Hughes receiver, and my TV is a Tosh. TW40X81. If this is normal I might not keep it. Very low WAF. I went through the old threads, but can't find one with the exact symptoms. Thanks in advance guys.
