Hi, it happens also for me - when I try to go in to my YouTube account, box reboots and resets to factory defaults.
And today friend of mind has bought this small box, Netgear EVA2000:

Remote looks exactly the same. And this box has much more net-video functions, and, of course, you can log in to your YouTuve account
I started to feel quite big disappointment, because I already have this WD TV Live.
