Yes, that's the one....
So, what's the difference between WD TV Live Streaming Media Player and WD TV Live? Except for the not-supported by WDLXTV part.
Isn't the WD TV Live Streaming Player the new version of WD TV Live? I mean, there is no other WD TV Live to buy at the moment except for the one that I've just bought... Actually, there is WD TV Live Hub but that's a different device.
The Live Streaming is replacing both the Live and Live Plus models. It's based on newer base code (closer to the Live Hub than to the former two), with a more modern UI, and more online services available. But the downside is WD is encrypting large portions of its firmware, making it nearly impossible for us to put WDLXTV on it. At this point the only advice we can give to WDLXTV supporters is to return the device, and make sure you let WD know the reason of your return (the removal of any homebrew firmware possibility). There's a thread discussing that device here: http://forum.wdlxtv.com/viewtopic.php?f=33&t=5991
Let's face it: without WDLXTV, the WDTV line of product would be just "yet another media player device" lost in a seas of competition. It doesn't has any real advantage over the (often cheaper) competition outside of maybe a slightly better image quality. And a bunch of online services, most of which are only available in the US. So if the WD ties want to appease the Hollywood Gods at all cost, then... so be it. The day the dev team spots a competitor's device that is more open to homebrew and b-rad decides to throw his weight behind it, the only losers in the end would be WD themselves.
