Suddenly (last couple of days) I've noticed one of my two Hoppers With Sling misbehaving. I first noticed when PTAT didn't record. I checked the daily schedule for Monday, and it said PTAT was "Deleted by user livingroom". Nope, nobody deleted anything. Any why can't I watch locals? It seems tuner1 and tuner2 are OK, but tuner3 is frozen. If I change channels from the frozen image, I get a black screen. So long as I choose something outside the locals, tuner1 or tuner2 is brought into play and it works fine. So I reboot. Everything goes back to normal. Next day (Tuesday) PTAT records OK. But just when I start to think it was a glitch, local program on channel 4 freezes this morning. Press red button - yep, tuner3 is hosed. Everything else works. This has repeated a number of times today. I had to configure the upstairs Hopper to grab PTAT for a while. Now I have to contact Dish and get this thing replaced. I've tried pressing the red button, pressing the "reset" icon in the settings, even unplugging power/plugging it back in. After a while tuner3 freezes again. Anyone else seen this? I suspect a firmware update triggered this, but alas there's no "when did this thing last update" log (or is there?). Also I can't roll it back to a previous version as a test. So now I have to save all the recordings onto an external drive before they come to take it away. These things have been fairly reliable up until now.
