Hey everybody, i have a Viewsat extreme and from today morning all i can see is green pixels on the screen..the signal strenght is almost between 75-80 but the quality is very low..almost 20..what should i do to improve the quality..if i have to manually change the angles of the dish...then i cant do so immediately as the dish is on the rooftop n its currently snowing out here in mississauga..does that mean that no dish network for me till its sunny n warm n i can climb up on the rooftop again??? plz any help will be appreciated
