DVD/Driver problems on my laptop?

I have an XPS m140 series laptop computer and i am having trouble with my DVD player on my laptop. Everytime that i try to play a movie, this message comes up. 'Windows Media Player cannot play this DVD because there is a problem with digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card.'

The problem is that when i go to the site that it tells me to look for an update at, the site doesn't have any updates for my driver. If you have had this same problem and you have ANY idea on how i could fix it, please let me know. Thanks for your time.
