As a long time suscriber to DirecTV some time ago I "upgraded" to the oval dish/HD DVR system. Since then I have had the receiver replaced twice, the LNB's, B-Band converters and coax replaced, etc. My problem, intermittant pixelizing on some HD channels and local stations, is still ongoing. As of today DirecTV refuses to honor my Protection Plan saying that I must call when the problem occures and go through a trouble shooting procedure with them or they will have to charge for a service call. My problem, when it occurs, only lasts for a minute or so and then clears up. By the time I call and get through to a tech rep the problem will have corrected itself. How should I handle this situation? I am very frustrated!
