Seperating the audio track

Good day, running XP Home SP2
I have a nice DVix rock video, but only have an mp3 player. Is there any software, shareware, freeware that will rip the audio track from a DVix video file so that I can save the audio file separately.

You can find extensive 'how-to' guides at AfterDawn. Here's a guide that requires the use of VirtualDub Mod which is different from the version available here at MajorGeeks. Click this link http://www.afterdawn.com/guides/archive/extract_ac3_from_avi.cfm and you'll see what you need to do.
