The installation is done and you signed off on it. There is no way Directv is going to come out and trim your trees for you. You might as well just relax and at some point get those branches trimmed way back. I know it is not what you want to hear but it's what you have to deal with at this time. Just take it as kind of a "lesson learned" thing, and make the best of it. Other than those branches you have nothing to worry about, you will love Directv and everything else will be just fine.
