I just got the WD TV Live Hub and have done alot of testing.
wdtvlivehub_2.05.08 was the first thing I did.
Netflix Canada works GREAT.
The DWA-130 H/W Ver:B1 F/W Ver:2.00 seems to be completely unsupported as when plugged in nothing happens and the setup will not even see it. The light on the device never turns on.
