I use Audacity <http://audacity.sourceforge.net/> for all my sound editing (and when I say "all" I mean "the handful of times I have wanted to crop a segment of a song to use a ringtone" :P). I'm pretty sure it has a noise removal function built-in.
I don't think it understands video file formats though, so you'd probably need some other tool that's capable of extracting the audio stream from the file.
