Converting .rmvb to .avi and removing narator voice over

I got a film which is in .rmvb format and i was just wondering how i would remove the narator’s voice over in a different language once i’ve converted it to .avi format or mpeg. Any help is much aprreciated.

Why don’t you ask the creator of that file?

Should be easily muxable after you have got all streams…

well i would if i knew the creator of the file…

any ideas pplz?
