Almost any distribution will play DVDs, it's just a legal restriction in some countries that the required software can't be included. The problem is that Linux distributions are free, and the ability to use the hardware you paid for to play the movies you paid for is licensed. Since no one is collecting the license fee, the distribution can't include the software without risk of being charged with "contributory infringement". Google most any distribution and DVD and you'll find the instructions.
