Just bought the SamsungUN55D6000 smart TV and was excited by the fact that netflix was integrated. I do have one of the original Roku boxes which is now moved to the bedroom TV since I have this new feature. Playback of movies and tv shows isn't what I was hoping for. While the quality is good and I don't have a buffering issue (at least it doesn't drop out to the loading screen), I do get intermittent flashes of black screen throughout the playback. It doesn't happen the entire time but occurs in spurts, and enough to be annoying. I don't see any mention of smart tv probelms in this form or at samsung's site. Does anyone else experience this and is there something I can do?
