I have been getting problems when viewing certian channels. I'm having a hard time getting versus, mtv, nfl network and Speed. Sometimes the HD channel won't come in but the SD channel will. A few months ago I had a tech come out and he found that when the installer installed my dish (in feb) he didn't take into account that when it starts to warm up leaves grow on trees which will disrupt my signal. And when the leaves fall I won't have a problem. But 90% of my channels come in but a few have "complete signal loss". Now if the tree is affecting my service wouldn't it affect it as a whole not just certain channels?
