Yes - this was a really nice surprise to find in the Google App store yesterday!
Runs fast and smooth on my Sony Bravia with Google TV 8. 1080p/50 with 5.1 sound with Boost and, most importantly, eliminates the problem I had with my Youview box app (sound dropouts which are a widespread problem on that device).
The Bravia does have Chromecast but did suffer a dropped frame judder when using that method. The native Android TV app however is as smooth as silk!
