voice removal

We have a conference coming up next week for all of our senior staff and directors. 

Greetings. I'm looking for a filter or tool that can remove the music from a live video source (e.g., a NASA broadcast), while leaving the voices and non-musical noises. It doesn't have to be perfect, but it needs to remove/mute enough of the music to avoid triggering YouTube's copyright detection, and not mess up the voices too much.

id like to record a song with my mic, for my girlfriend, but i need to get the music from a mp3 without the original singers voice...



should i get audicion? acid? cubase? edit pro?



do you have any tutorial that i could see how to do this?

thanks alot

Hey, does anyone know where to get a VST plugin that removes the vocals from songs? I have found some on the net but they dont do the job very well at all.



Thanks
