Any improvemnt on the sluggish interface? Even if Sammy did realease an update, it's possible that updates to the 34 might improve performance. The reason I ask is that I'm about to pull the trigger on the UN46D6000S this week when the tax return comes. I'll still probably get it, but I'd feel better if I knew there was improvement. Also I have another question: does the RVU protocol support 5.1 Dolby Digital for the client TV? If so, I assume it passes to a receiver with the television's toslink/optical connection?
