Ultrasonically Faring Statesmanship - Sowing The Seeds Of Love

wrong DVD's

I bought some DVD’s for the children a few days ago. I tried them in a few DVD players but they did not work. How strange! What do I do wrong? This afternoon I went back to the store where I bought them. I was lucky I saved the invoice which I don’t do always. In the store there was a very nice man and he asked me what is wrong with the DVD’s. I explained that I tried them on several DVD player but they did not start playing. He tried it in the store and they start playing immediately. I was very surprised. How is that possible? Then the man asked me if I tried them in a blue-ray player. Oh, I bought blue-ray DVD’s and they don’t work in a normal player. Now we have to buy a blue-ray player.
