I received another supplier, and it did the same. Neither play on my portable player or my computer. The team is the box containing the blank CD. In the laptop screen remains blank, and after a few minutes, no longer turn the DVD. I have no problems playing other DVD on your computer or laptop. I contacted the seller and do not know what the problem could be.
