The blu ray disk did not play at all on my Samsung player, even after 2 firmware updates. It's played ever other blu disk I've thrown at it.Amazon is not allowing me to return it for a refund.What a rip off.Stay away from Blu Ray! Amazon should update their return policies.Blu ray disks that only play on some players should LISTED WITH WHICH PLAYERS THEY SUPPORT.
