VLC Media Player 1.1.9 2011

The best multi-format media player
If you want to play video or music files and not worry about format, VLC Media Player is the best application for the job. With so many media formats out there, VLC Media Player is a catch-all player that can handle anything.

If you're looking for a great alternative to Windows Media Player, iTunes, RealPlayer and others, VLC Media Player is the application you need.

Now in its 1.0 release, VLC Media Player is simply the most stable, flexible and lightweight audio and video players around today. While other media players will play unusual formats after downloading a codec, or simply refuse to play things, VLC Media Player covers tons of formats, from MPEG to FLV and RMBV files. In addition to this, you can also use it to preview files you are downloading, because it will play parts of files. It takes no time to start up either, so opening it up to preview something is no trouble at all.
