How to extract secondary audio track (muxed)

[T90]

I need to extract the secondary audio track from a divx movie. I tried Nandub, but it seems to extract only the primary track. How do I do it?

The only method of which I'm aware would be to use Graphedit to switch the two audio positions, save the revised DivX-compressed .AVI and then use VirtualDub or NanDub to extract the (now) primary audiostream...
