Permanently filtering one audio track?

[BayouBecky]

I have an AVI file on my computer that has the audio in both Italian and English that plays at the same time. I found the option to filter the Italian out so that only the English is audible, but I'm wondering if there is a way I can strip it out permanently and save the file without it, so I can use another program on my computer to burn it to DVD. Can anyone help me or do I need to give more info before that's even possible?

Thanks so much for any help you guys can offer. I'm feeling extremely computer illiterate at the moment, and definitely clueless. LOL
