初次使用ppstream，有如下的问题

点击某个电影，缓冲文件之后即可停止播放，
并跳到下一个电影继续缓冲，如此继续。。。

接着终端执行PPSteam，发现

不知是何错误？

ldd看一下ppstream和它带的mplayer有没有可疑的地方，我之前也遇到这个问题，好像是必须要libpng1.2，我系统里原来的libpng1.5，就算是做了一个软链接也有问题。emerge libpng1.2就能播放了，而且如果不用自带的mplayer也有这个现象

确实如你所言，现已正常！
感谢。

难道你们都没有遇到无限重复要求root密码升级并且退出的问题吗？我都快郁闷死了

可能还是和lib版本有关吧，我在Debian sid AMD64的机器上搞ppstream的过程中遇到过，因为有些32位的lib是自己从i386的包里手动提取出来的，后来发现要用Stable分支里的包，lib都OK了就没问题了
