It's changing channels like the channel down button is stuck, I pulled the remote batteries while this was happening and it continued. I was not recording anything and the dish remote is the only remote in the room.
Very strange behavior. You can rule out other Hopper and Joeys in your system as the cause since there is no way they can affect what's being shown on the kitchen Joey.
It's possible something in the kitchen may be generating a spurious button press via IR. To rule out IR interference, go into the menus and turn off IR (if you aren't using it). If problems persist (or it's already off), look for problems elsewhere.
Go to the system status menu (MENU twice on the old U/I, three on the new) and see if there are any other remotes paired. Again, this is a long shot since a button would need to be pressed and held on another remote to cause what you are seeing. While you are there, check the battery condition of the remote. If they are getting low there is a slight possibility replacing the batteries will resolve the problem.
If the Dish remote is generating a spurious button press without a release, removing the batteries from the remote might not stop the channel changing. The batteries would need to be removed before the remote has a chance to issue the button press. In other words, you'd need to keep the batteries out of the remote except when watching the kitchen Joey. That's probably not convenient.
Probably the easiest thing to do is swap remote for the kitchen Joey with another Joey or Hopper and see if the problems move to the other location. If so, it's the remote. If the problems persist on the kitchen Joey, it's most likely a flakey Joey. Dish should replace the flakey unit whichever it is.
