I just got Dish with the 622 and I'm having a problem with the TV-2 output. The audio is very low. I have to turn the TV all the way up just to get marginal volume. And there is an RF buzz that comes and goes. Sometimes the buzz will go away if I touch the TV, and other things seem to affect it as well. The TV is in a room full of other electronic stuff, computers etc. I turned off all the electronics I could and the buzz persisted. The cable run is approximately 50 feet. Thanks for any help.
