just had my hopper 3 with 3 joeys installed yesterday. Had a couple of concerns.. One of my joeys kept showing the "press select to watch tv" screensaver come on every 4 mins or so. Dish had me reset the hopper then the Joey to clear it up. I know the hopper 3 is brand new so is it common to have errors like this when equipment first launches? I also noticed Netflix app was sluggish on other joeys. Takes a long time to load and picture is very pixelated for first 3 or 4 minutes. Would it be beneficial to hook up cat 5 to the joeys? I have my whole house wired in every room. Dish tech support said the joeys should communicate to the hopper via the coax. Does this seem right?
