[求助]怎样用Nandub分割avi文件

软件版本：Nandub-1.0rc2-YUY2lumECFfix
正常解压后，运行Nandub.exe，file－>open video file，打开avi文件时会弹出对话框Nandub errer：Couldn't locate decompressor for format‘DIV3’(Microsoft High-Speed MPEG-4 V3[Hack: Divx Low-Motion])
Virtualdub requires a Video for window (VFW) compatible codec to decompress video.DirectShow codecs,such as those used by Windows Media Player,are not suitable.
请问如何解决。
很急的说，谢谢。
