That must not have been the case everywhere. The only extended issue I've had with Netflix was when the Premiere was first released. Otherwise streaming from Netflix on the Premiere has been reliable for me. I've had no issue in the last few months with it that I can recall. And if there was it was isolated to a short time period..
My main beef with Netflix on the Premiere is with DD+. Sometimes it will output DD and sometime DD+. I can try the same title several times and sometimes it will be DD+ and sometimes DD.
