Menu freeze up, picture freeze up... One morning it just wouldn't boot up at all with the remote, so I booted it with the power switch and it still would not react to the remote before I reset it. I called the Tech Support people the first two times, and their answer was either unplug it and plug it back in, or push the little red reset button, so that's what I've done since.
BTW we don't have any Joeys hooked up, it's just the Hopper by its self. It is set up on our WiFi network, and has updated at least two times I know of, maybe more. But, I just had to reset it this afternoon before I made this post. I was scrolling through the channel guide and it just froze, locked up tight, so did the picture feed in the little screen preview box. But, no error messages.
