VLC is widely used to watch movies and other files that can't be opened in WMP. It contains all codecs to load these files, that's why we also use it on some P2P programs.
VLC is a free and open source cross-platform multimedia player and framework that plays most multimedia files as well as DVD, Audio CD, VCD, and various streaming protocols.
Just download and install it.
