SMPlayer is a free media player for Windows and Linux with
built-in codecs that can play virtually all video and audio
formats.
It doesn't need any external codecs. Just install SMPlayer
and you'll be able to play all formats without the hassle
to find and install codec packs.

One of the most interesting features of SMPlayer:
it remembers the settings of all files you play.
So you start to watch a movie but you have to leave...
don't worry, when you open that movie again it will be
resumed at the same point you left it, and with the same
settings: audio track, subtitles, volume...

SMPlayer is a graphical user interface (GUI) for the
award-winning MPlayer, which is capable of playing almost
all known video and audio formats.
But apart from providing access for the most common and useful
options of MPlayer, SMPlayer adds other interesting features
like the possibility to play Youtube videos or download
subtitles.
