Hi guys,
Have one of these boxes for about 6 mths now.
Reading the freeze , reboot probelms here, thought I would add my experience if it may help anyone.
I found some of the firmwares caused probelms as was reported, but noticed this box is sensitive to heat, even on a very open shelf with plenty of space nothing on top or around that in time it would freeze, xbmc wouldnt work, i found that this stopped when not sitting on top of my other reciever, so I have it sitting on its own, but thinking because of this (as with some dm800`s) i plugged in a laptop cooler to the usb and put it underneath(was working ok without, but just had one sitting here).
My firmware is not the latest its about 2 back but seems stable these past months.
