我喜欢用绿色版的软件，绿色版的TMPGEnc 4.0 XPress，绿色的KMPLAYER，之前想导入RMVB必须使用莫尼卡安装版的KMP、或安装REAL在线播放组件，或安装REALPLAYER以后才能正常导入RMVB文件。经过数十次恢复系统，多次实验后发现：其实TMPGEnc 4.0 XPress导入RMVB只需要两个文件。RealMediaSplitter.ax和Pncrt.dll

　　1、RealMediaSplitter.ax，RealMediaSplitter.ax必须注册，最佳版本是1.0.0.9,用高版本的总会莫名奇妙出错。但1.0.1.0的兼容性比1.0.1.1兼容性好，前者出错率约5%左右，后者出错率最起码40%。

　　2、Pncrt.dll必须在system32目录下，如果缺该文件会造成导入的RMVB无声音（多次试验的结果）。符合以上两条件以后还必须导入一个注册表才能正常使用导入RMVB功能。

　　3、导入注册表，其中红字需要修改为RealMediaSplitter.ax所在目录.（注意注册表中的路径是双斜线。将划横线的下面内容保存为REG文件就行了。比如REAL.reg）。

　　4、导入完毕后就大功告成了。
