Ive had my Dish 1000.2 installed for about a month now and wondered if a slight pixelation is normal a couple times every hour or so on the HD channels, no matter which HD channel it is. Its not really enough for me to get all "up in arms" about but it is a slight concern. I have no obstacles anywhere near my dish. Does it need fine tuned? my zip code is 48507 if that would be of any help.
