Unit is out of warranty of course. Plays dvd discs fine, but won't play any blu-ray discs. Get an error "this disk cannot be played". I have unplugged it, reset it (using remote). Reset it using controls on player itself. Jumped up and down 4 times, and circled my sofa 3 times. I have put 3 needles in a bar of soap i carved to look like a blu-ray player, but nothing seems to work. Samsung support of course couldn't care less. And, I just uploaded the latest firmware, to no avail.
