MacBook won't play DVD

[Islandguy]

MacBook about 1 yr old. It has been great playing DVD's. But I have this one DVD which the Mac won't play. I also tried it on my friends MacBook...no go. But the DVD does play on my PC's and my home DVD player. I made a copy of this DVD on my PC and tried the copy...no good as well. The MacBook does not recognize it. The DVD player never launches. I have to reboot the MacBook and hold down the mouse key to get the DVD to eject. Any help appreciated.
Thanks,
Jim

Tried the mystery DVD on a few other MacBooks and none of them recognize the DVD so...I just gave up and watch it on my PC or DVD player. Must be some type of formatting issue?

is it a new commercial DVD? Maybe a newer DVD has some sneaky copy protection stuff that OSx doesn't recognize the disk at all.

Not that I am aware of...been out since 2006.
