Very nice app. Just tried it with my new WDTV live (not the Hub one), and it works fine.
Auto detects your WIFI connected devices at startup -> just select your WD device.
Very convenient keyboard feature.
One flaw according to me: when entering a login/password with the keyboard feature, need to press "submit" once on the in-app keyboard, and then once again on the WD device keyboard (cant submit directly from the in-app keyboard)
