OK....So I have a Hopper with Sling with one Joey and one Super Joey. I upgraded to Hopper w/sling about a month ago, and from the beginning it works fine for a while, but the more it is doing, like recording, somebody watching a recording, etc... it often times starts getting sluggish, or it goes black screen and eventually reboots. So...I just got a replacement Hopper w/sling and this one is doing exactly the same thing. EXACTLY! It makes me think there is something else in my system that is causing this. I have good MOCA on all units and joey and super joey work fine as long as the Hopper w/sling isn't acting up. I thought maybe overheating, but my maximum temp is 116. Any ideas on what I can try? Very frustrating.
