Too Many Soundtracks

[thevogue]

I have a movie that has the video that has two sound tracks the english and some other language. The English track is in sync with the movie and I would like to just get rid of the second language. Is there any way to do that maybe with virtual dub?

Nandub should be able to do the job.

Just select
Audio->'Secondary stream'->'No audio'
Audio->'Avi audio'
Audio->'Direct stream copy'
Video->'Direct Stream copy'

And save that.
And remember to check that the correct audio stream has been removed.

It won't work though if the soundtracks are 'welded' together under one audio stream. In that case, you're out of luck. Or does it happen that one soundtrack is output on the left channel and the other one on the right channel?
