2 languages in one movie, want to chose 1 only :(

[raladin3d]

Hello guys.
will try to make this short.
I have an episode of a movie that it came with 2 languages in it, English and Japanese.
I can switch between those 2 through VLC, press right click with the mouse button, the choosing the language.

However, I want to convert the video into MPEG, when I use a program to do so, it converts to me the English version of it, and I cant switch between the languages no more
But I want the Japanese language (DUB) one, not the English.
so how can I make VLC or the converter to understand that the main language in the video is the Japanese language not the English 1, and that I want to make the MPEG output file with Japanese language(DUB) only?

please please help, this is important to me
thanks

vlc --audio-track 2
or something like that I guess.

If you don't mind the output being MP4, then take a look to see if Handbrake (open source) can help. I have already used it to convert DVDs with multiple language tracks to MPEG4 video with multiple audio tracks intact. Assuming MP4 again, Subler (open source) can be used to insert extra audio tracks.
