VLC Media Player for any platform

VideoLAN - Free Software and Open Source video streaming solution for every OS!

Ever download something, open it and it doesn't play? Well the great people over at videolan have created the best video program ever!! VideoLAN will play anything no matter what the codec or file type. It can do divx, xvid, svcd, dvd, and just about anything else you can name. It works great with Mac OSX and it is a great solution to having to load a billion codecs in Windows XP. This is the best free video playing software I've ever seen.
