Linux下最棒的全能播放器MPlayer已经被移植到windows mobile下，下面是引用作者的文章：
Hi All,
This is the mplayer (famous linux media player ) port for Windows smartphone . I have tested this with Application unlocked SP5m ( WM6) . It should run on all windows smartphones as well Pocket PCs with QVGA display (240x320) , I have not verified with landscape display but it should work. If you find any bug on landscape screens please inform me.
Installation guide..
Unzip all the contents to memory card and run mplayer.exe , All files should be in same folder.
Advantage of mplayer
-- Full support of streaming
-- supports all real media formats including streaming.
-- Supports RV40, RV30, R20 , sipro , cook and atrac codecs.
-- Supports MP4 streaming over RTSP.
-- All flavors of Flash video are supported.
-- Uses coremp4 for MP4 decoding.
TODO:
-- Need to imporve GUI ( current version is just for preview)
-- WMA decoder is not supported ( Need to add windows DMO driver, any help will be great)
-- Need to fix some crashes .
Overclock your tornado to 240 MHz , this will give best result.

作者下一步要改进的有：改进用户界面；使其支持WMA；解决一些存在的问题
经本人测试，已知在中文系统的问题有，不支持中文路径，文件名不能使用中文字符，不过在播放ＦＬＶ方面比ＴＣＰＭＰ进步的一个地方就是可以快进快退（转IOICN）
