removing one audio track from an avi movie file

[srckaimal]

I have an *.avi file with 2 sound tracks. Russian is predominat but I can hear the original English in the background very softly. I don't know Russian. Can Avimux drop the Russian and enhance the English? When I open the file in AVImux this is what I get.
audio MPEG 1 layer 3(CBR 128 kbps, 2ch, 44100Hz,92.4Mbyte)
video Four CC XVID(824kbps,595Mbyte,1 40 54)

When I open the file in virtualdubmod, only one audio stream is shown

How can get rid of the Russian audio?The movie is 'Other people's money'

Thanks

Go and buy a legitimate version, because the one you "acquired" cannot be fixed.
