错误提示是：
could not locate decompressor for format "mpe2"(MICROSOFT HIGH-SPEED MPEG-4 V2)
virtualdub requires a video for windows (VFW) compatible codec to decompress video. directshow codecs,such as those used by windows media player,are not suitable.
我重装了FFDSHOW和DIVX6之类编码器的情况依旧，由于我对编码之类的不太了解，还请大家指点指点了。谢谢！
