SMPlayer intends to be a complete front-end for MPlayer, from basic features like playing videos, DVDs, and VCDs to more advanced features like support for MPlayer filters and more. It's packaged in PortableApps.com Format so it can easily integrate with the PortableApps.com Suite. And it's open source and completely free.

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 resume at the same point you left it, and with the same settings: audio track, subtitles, volume...

Other additional interesting features:
* Configurable subtitles. You can choose font and size, and even colors for the subtitles.
* Audio track switching. You can choose the audio track you want to listen. Works with avi and mkv. And of course with DVDs.
* Seeking by mouse wheel. You can use your mouse wheel to go forward or backward in the video.
* Video equalizer, allows you to adjust the brightness, contrast, hue, saturation and gamma of the video image.
* Multiple speed playback. You can play at 2X, 4X... and even in slow motion.
* Filters. Several filters are available: deinterlace, postprocessing, denoise... and even a karaoke filter (voice removal).
* Audio and subtitles delay adjustment. Allows you to sync audio and subtitles.
* Advanced options, such as selecting a demuxer or video & audio codecs.
* Playlist. Allows you to enqueue several files to be played one after each other. Autorepeat and shuffle supported too.
* Preferences dialog. You can easily configure every option of SMPlayer by using a nice preferences dialog.
* Possibility to search automatically for subtitles in opensubtitles.org.
* Translations: currently SMPlayer is translated into more than 20 languages, including Spanish, German, French, Italian, Russian, Chinese, Japanese....
* It's multiplatform. Binaries available for Windows and Linux.
* SMPlayer is under the GPL license.

The latest version is 0.7.0
* New favorite menu, where you can add your favorite videos, music, streams, youtube videos... It's also possible to add submenus.
* Support for youtube. Now you can open urls like using the Open - URL dialog or dragging a link from a browser to the smplayer window.
* Support for mplayer2. It's a fork of mplayer with interesting features like precise seeking, ordered chapters in mkv videos and better pause handling (e.g. seek works while the video is paused).
* New translation: croatian.
