If you research BluRay they have a system of copy protection (the studios, not Samsung) and they change it to try to keep ahead of the pirates like an arms race. Frankly I found the entire situation unacceptable and my BluRay collection is up to all of 6 titles.

So why can't anyone but Samsung and the studios fix this? Because the firmware in the players need to be revised with each new copy protection the studios deploy.

At some point you see where manufacturers will start telling us our players won't be updated. If this is not an old player and say in warranty I'd try to return it for a new model that plays the titles. Repeat that as long as you can.
