Free DVD player program?

[stratusmatt]

Hello I bought a computer from a friend of mine that was screwed up and i zeroed it out and started over from scratch he didnt have any softwear or it so I had to barrow the softwear from friends of mine a disc here and there, but none of them have a DVD player. Windows Media Player will not play my DVDs and I was wondering If there is a free program online that i can downoload? I would appreciate any responses Thank you.
