Newbie to the forums...discovered it an hour ago, and just joined. I've had a Sony system since '96. Standard 18 inch antenna with dual LNB, with each line feeding a receiver in different rooms. This setup works fabulously, but a problem has developed in the last 1 1/2 years. When I press display on the remotes, the program description will come up with the letters garbled about half the time, and usually with a long string of the letter "z", kind of like zzzzzzzzzzzzzzzz. this happenned with both receivers. Is this a DirecTV problem or is it a problem with my equipment? Any ideas? Thanks in advance.
