For the last 6 months, I have been facing frequent pixellation on many channels. I have the latest Zenega STB. First, the technicians came and adjusted the LNB. But nothing improved. Then they took the STB and said that they reprogrammed it. Still no luck. Then STB was replaced. Still no luck. Today, the Dish and LNB was replaced as well. The freezes and pixellations are a bit less. But still there. So far, I have spent close to Rs. 2000 in whole process and yet I am not satisfied with the picture quality. Almost everything is new except the cable. The service fellow refuses to replace the cable since its concealed.Do others see some picture freezes as well? All the transponders are showing signal quality of 80 or above. Signal strength is between 70-80. Any ideas? I dont want to abandon DishTV since I have been using their service since they started almost 6 years ago. Now spending all this money, I feel I should have switched to some other service provider. I am in the Pune area.
