Lil help converting a Divx file

[PsychoPops]

Lo all Im having a lil problem figuring this one out. I downloaded shallowhal divx and am trying to convert the audio with virtual dub and am getting errors he file plays fine in media player I.E getting sound and video but when I try to convert audio to wav with vdub it gives me the error
the requested audio compression is not compatible with the input format
check that the sampling rate and channel count of the input match those of the requested format
get the same error with soundforge even trie Ulead media studio and it just flat out says unable to access audio codec driver
I have tsunami codec pack installed and the elecard 140 codec when I look in file properties of media player it looks like its using the iviaudio.ax to do audio any help would be greatly appreciated usually dont have this prob I usually am able to convert divx audio to wav with no prob
