Kantaris is a capable, free video and audio player, based on the code for VLC Media Player.
The program can handle all the main video and audio formats, then, as well as most of the minor ones, without you having to worry about whether you've installed the right codecs. And of course it's just as happy playing audio CDs, video DVDs, even internet streams.
Open a particular file and Kantaris will automatically fetch the appropriate album or movie art from sites like Amazon, Last.fm and Imdb.
The program can automatically find subtitles for some video files.
You get some top quality visualisations.
And new support for plugins allows Kantaris to be extended with interesting new features. So you can watch the latest movie trailers; search and play music directly from the web; organise your audio and video files in a library; listen to podcasts, and more.
It's had some bugs in the past, but Kantaris seems more stable now. It also handles most media formats very well, and the new plugins are particularly interesting. If you're tired of your current media player, this one just might be worth a look
