OK, so I had an HR20-100 and it went down, so D* sent me a new reciever (HR20-700). I get it setup/activated and go through about 3 channel tests with the customer service rep....everything is fine. The FIRST channel I go to after I hang up is ESPNHD and I get crackling audio (hard to explain, but probably compared to video pixelation). I switch from HDMI to component....same thing. Anyone else experience this??? BTW, this happens on most HD channels and some SD channels (completely random)....They are sending another tech out Monday, but just wanted to see if anyone else had this happen.
