Why don't you try outputting the english track to frameno.avi in the 
same folder as the movie, and do:

   mencoder -oac copy -ovc copy  IN.avi -o OUT.avi

If that doesn't work, you could dump the audio to some normal file, like 
an MP3, then just add "-audiofile ENGLISH.mp3" to the above command.
