mplayer与realplayer播放的问题

allwin

我配置mplayer有点问题，始终不能用,realplayer 10可以用，但只有图象没声音，而且不能播mp3
具体情况是：我的系统是redhat 9,显卡是集成的sis 315芯片的sis
740显卡，由于sis对linux官方不支持，没有正式的驱动程序，刚装上系统时用的是统一的vesa驱动程序。
后来我到http://www.winischhofer.net去下了一位爱好者做的sis的驱动，显示效果确实明显改善。
一年前我用的同样的驱动程序，配置了mplayer 0.93(似乎是这个版本),当时可以播放视频，可以使用mplayer
现在我配置mplayer pre1.5,始终不能用。
用glxinfo查看显卡信息，标准输出文件如下：
