... and MPlayer2 as backend, Startbuck's FreePlayer is fast and powerful. Another great feature of MPlayer is the wide range of supported output drivers (X11, Xv, DGA, OpenGL, SVGAlib, fbdev, AAlib, DirectFB, GGI, SDL, VESA). Most of them support software or hardware scaling, so you can enjoy movies in fullscreen.
Not just a MPlayer GUI, Starbuck's FreePlayer includes a full-featured video web browser and it can save audio and video network streams to your local filesystem.
