Why doesn't the DVD work in my DVD player?

[Madi]

I hired a DVD from the DVD shop, so it's not made for the computer or anything.
It works on the computer, but not on the DVD player. There's nothing wrong with the DVD player because other DVD's work on it, there are some little scratches on the DVD itself, but they're not bad or anything.
Why doesn't it work and how can I make it work?

OTHER DVD'S WORK ON THE DVD PLAYER, HOW IS IT BROKEN?

[Niikkaa]

It could be broken..
Try buying something else.
