I HAVE BOUGHT SEVEN DVD'S FROM AMAZON.COM WITHIN THE LAST FEW WEEKS (AND I REALLY WANT ALL OF THEM !) AND SIX OF THE SEVEN DO NOT WORK IN MY DVD PLAYER. MY DVD PLAYER IS A MODERN ONE, I HAVE HAD NO TROUBLE WITH IT , AND IT PLAYS OTHER DVD'S THAT I HAVE . WHEN I TRY TO PLAY A DVD THAT I HAVE BOUGHT FROM YOU, THE RESPONSE IS"THIS DISC DOES NOT WORK. CHECK YOUR DISC".BOTH MY TV AND MY DVD PLAYER IS "SAMSUNG".......AND THERE IS REALLY NO REASON WHY THE DVD'S DO NOT WORK. PLEASE HELP ME WITH THIS .......BECAUSE I REALLY WANT THESE DVD'S.......AND THERE IS NO REASON WHY THEY SHOULD NOT WORK.I WILL BE GLAD TO GIVE YOU ALL THE NAMES OF THE DVD' S THAT I HAVE RECENTLY BOUGHT. (AND THEY ARE ALL NEW DVD'S). AND PERHAPS WE CAN FIGURE OUT WHAT THE PROBLEM IS, BECAUSE I REALLY WAN TO KEEP THESE DVD'S. THEY ARE ALL CLASSIS MOVIES, THAT I REALLY WANT. THANK YOU. ROBERTA BABCOCK
