Frequent loss of signal; Screen glitches during playback

We have been having major problems with signal loss lately. It happens on only certain HD channels.Weather is not the issue. I have a feeling the answer is that someone needs to come out to re align our dish but wanted to ask. Also, we are having another issue which I'm not sure if it is related or not but when we watch recorded shows we frequently come across where the picture jumps/skips/glitches/freezes. This problem seems to happen during programming where there is a lot of noise--cheering, singing, etc. Signal strength test results are below. Thanks!
