I have had mine since April 9th, works great no reboots, Use HDMI, componets and coax all hooked up, optical.As well as Ant for OTA/HD. Locked up once while my son paused cartoons.Just turn it off and on. But other then that no problems. I sits in open air so it's cool and I had a wisper fan blowing on it to help with the heat, heat is a problem that can cause all kinds of issues. Also I use mine in single mode most of the time. As for install D1000 feed two receivers on 4 T.V.'s. I bought a DPP44 switch and had installer hook it up when he was here, based on the reading I have done haveing the powered inserter seemed to not hurt, And I got it for a good price hope this helps. FYI
