I have white jagged lines that are to the right of all letters and the image on ESPNHD only. I just activated the HD package yesterday on Dishnetwork and the other channels look fine. Dish has no idea what it could be and my brother who lives 20 miles away and has the exact same equipment says it looks fine at his place. Any ideas? I have a 55 in. Mitsubishi and a 6000 receiver with 8vsb and 8psk.
