audio probs. when cutting avi w/ virtdub

[Pht]

Hi all and thx for your time
Ok so I've got this avi (divx4, low motion) that I need to cut to fit on a couple of cds (using nero svcd plugin to burn). Well I dl'd virtual dub and tried cutting the file as per the how to on divx digest's web page... and the audio winds up being way ahead.
Yes, I tried the fix on the page for audio out of synch, and when I do that Vdub whacks the file down to like the last bunch of frames and no audio. Now I know I ain't no genius but I'm not the dullest tack in the box, and I can follow directions.
Any help would be appreciated

Virtualdub has problems with avi file using vbr mp3 streams, use nandub to cut instead.
