Thank you so much for posting this solution. I put in a movie this morning and was surprised that it would not play, even though the TV and CD functions played just fine. I entered the problem into Google as a Samsung blu-ray player problem, but it sent me to this c/net site and since I do have a Denon receiver I found that pretty amazing right off. When I saw your solution it seemed pretty easy to try and lo and behold the sound came right on!! Truly amazing and I am very grateful to you!
