I had a guy come out and fix my dish a few weeks ago. He moved the dish switched one of the parts on it (the MTU)and rewired my house (cause he needed work ) . But now one of my receivers has a problem. On some of the local channels lip sync is off and a few of my recordings get split. 17 Min /12 min type of thing. But it only occurs on my 622 not my 722. is there somthing in the options i can do or do i have to call them back out?
