How do I separate two languages froma an audio stream?

Hi. I downloaded an avi file but it was in russian. As it happens you can hear the english version in the background, miliseconds earlier than the russian one, in the two channels. I tried VirtuaDubMod but there is only one audio stream. It seems the english and the russion versions are in the same mp3 stream of the avi.
Is there a way to isolate the english version?

For what I know there is no way to do this :frowning:
