Can you create a WMV file with multiple audio tracks?

I'd like to ask if anybody know how to do this. I have a bunch of Karaoke DVDs which I'd like to rip into the computer and break them out song by song, so that it's easier to look up a particular song. The problem is the Karaoke has two audio tracks, one with the original singing by the singer, and the other one with just the music for doing karaoke. I'd like to create WMV file that retains both audio track and can be playback by Windows Media Center. Is this even possible? Thanks in advance for any information.
