[求助]VirtualDub-1.5.3的问题

大家好，我一用VirtualDub-1.5.3打开打开ＡＶＩ文件．就出现下面的字：
VirualDub Error
Couldn't loacte decompressor for format 'XVID' (unknown)
VirtualDub requires a Vedio for Windows (VFW) compatible codec to decompress vedio. DirectShow codecs, such as those used by Window Media Player, are not suitable.
有办法吗，如果能解决了,能告诉我下吗？

安装XviD
