I am getting 5.1 audio and XD video streams from the Viera Netflix app in the tv set. Exact same performance as the PS3 app. You can press the info button on the tv remote and it will give you stream details just like the PS3. I have had no problems yet with Netflix, Vudu or Hulu plus app. I haven't tried Amazon yet but will sign up for the free 30 day trial of Prime this weekend to check out.
