MPlayer is another movie player that can play most MPEG, VOB, AVI, VIVO, ASF/WMV and QT/MOV files supported by many native, XAnim and Win32 DLL codecs. In addition to this you can watch VideoCD, SVCD, DVD, 3ivx and even DivX movies. In this respect it supports more formats than any of the other players reviewed here.http://www.linuxjournal.com/article/5644
In addition to all of these video formats, MPlayer also supports a wide range of output drivers. It works with X11, Xv, DGA, OpenGL, SVGAlib, fbdev and AAlib, and you can use SDL and some low-level card-specific drivers (for Matrox, 3Dfx and RADEON) as well. Most of them support software or hardware scaling, so you can enjoy movies in full screen. Lastly, MPlayer supports displaying through some hardware MPEG decoder boards, such as the DVB and DXR3/Hollywood+. Blimey that's a list and a half.
