For the past week, my joeys have periodically gone to black screen when changing channels, and if I reboot the Joey it would come back. Even turning off the joey for a couple minutes would bring picture back. The DVR was acting weird when fast forwarding and skipping back, but I tolerated it, just thought there might be a glitch. Today, the Hopper3 started doing it. I unplugged a few times, then left unplugged for over an hour. After that, picture came back. But, no DVR. No pause, rewind, recordings, nothing. When I attempt to do anything, the message pops up "features using hard drive are not available at this time". I've never heard of that message so I'm concerned. Any thoughts? Thanks!
