Same case here. I purchased the app version 2.1 on April 7, 2011. I have WDTV Live Hub (internal 1TB HDD) with the latest official firmware version= 2.04.13.
The app can see the WDTV live hub only as a "Media source" but can´t play any videos or music. When I search using the browse button (browse worked once and then I can only use search) I got a message in the app saying "please select a wdtv device from the settings menu" or when trying to play a youtube video I get "No configured WDTV device".
In short I really love the idea of this app but actually is absolutely useless, it does nothing for me.
How to apply for a refund? or around when a new version supporting the wdtv live hub going to be released?.
I am not so angry for my $3 (no happy anyway) but mostly disapointed
I have not yet given any score in the app store and will refrain from it for a couple of weeks hoping to hear some positive feedback, like at least letting me try the "beta" version I read somewhere?.
I hope you have a chance to read this.
