I know this has been posted here, but it seems Dish engineers don't have a solution. All 3 of my Joey's have the voice out of sync with the picture. I haven't seen this since the 60's with Japanese Science fiction movies. I have restarted the Hopper, and all of the joeys, unplugged them, all to no avail.
So let's add this one to the pile and hope it gets some visibility to the engineers.
