I just had dish network put in a 2 room system with the dvr522. When connected with the supplied coaxial cables to the tv there are faint black lines that move from left to right across the screen and at times pixelization and blurry outlines of objects. When I plugged the supplied s-video cable into my tv the lines disappeared, but not the pixel problem. I tried switching the receiver and tv to channel 4 and that didn't help. When I checked the signal for the 119 satellite it showed over 100. Do you guys think if I use my old cable signal amplifier to boost the signal going into the receiver that might fix the issue? How about those in line rca satellite cable boosters they have at radio shack? Thanks for any ideas.
