Kantaris is an all new media player based on code from Videolan client (VLC) and Bass audio library. Kantaris has a graphical user interface similar to that of Windows Media Player.
Kantaris can play almost anything you can throw at it -- AVI, MPEG, MGEG-AVC, WMV, MOV, MKV, quicktime, matroska, divx, xvid, H264, MP3, WMA, OGG files and more. Kantaris can also play DVDs and audio CDs. The player also displays some of the most beautiful music visualizations ever seen. All this is completely free.
Fixed a serious bug where the player crashed when opening files associated with Kantaris in Windows explorer. Should have found this before releasing 0.2.3, sorry.
