最近买了一台ASUS的EeePC，同样的条件下，使用这台电脑在Windows下播放H264编码的720p的.MKV格式的电影的时候，是非常流畅的。而换到Ubuntu的时候，却非常非常的卡，不知道要怎么解释了。
我的设置使用的XV，播放软件是Mplayer，在Windows使用的是Kmplayer！
我不知道是什么原因造成的，初学linux也不知道该怎么分析这个问题。只能把我的设置给各位高手看看，和大家一起研究这个问题了。。。。。。。
我个人感觉是否会是linux的显卡驱动太过垃圾，造成这种问题，可是在更换不同的解码器的时候每种解码器的播放速度各不相同，所以又否定了这种想法，而且貌似ubuntu下的每种播放器的播放效果也不一样，所以至今还没想出个解决方案来，各位高手如果谁有招的话请告诉小弟我吧。。。。。。
以下是我的配置：
