New Samsung 3D 7 Series is stunning! The picture is brilliant(it took some tweaking),but for the life of me I can't explain the following;watching an old DVD(not blu-ray) like Whole Ten Yards the movement is absolutely smooth-no judder noticeable.Watching blu-ray The Dark Knight-picture is crystal as expected,but motion judder is so bad that the movie is nearly unwatchable.Changing between the MotionPlus options make no difference.One expects the opposite! Source is Sony 360 blu-ray player and DH 800 Receiver,both 3 months old.Premium Gold 1.3b HDMI cables.And can anyone explain to me what the LED MotionPlus is for? Don't seem to make much of a difference.
