Freeware to replace audio track on a video file?

[gastrof]

Is there any freeware out there that will allow me to replace the audio on a piece of video? (The thing runs about a minute and a half.)

I suppose something that people use to do music videos based on scenes from movies and TV shows would do it, but I have no idea where to look or what to look for.

If not freeware, then at least a recommendation for other software that'll do it?

What kind of video?
If AVI, VirtualDubMod.

We have no idea either, unless you tell us the format you are asking about.

For AVI type files, try VirtualDub.
