Changing audio track names in MKV files?

[MarcusRaven]

I have an anime my wife and I have been watching (Project ARMS), and we've made it all the way to episode 48/52. But now we have a problem. We've been watching these on WiiMC, and I have it set to default to the English audio track. This episode 48 file has a problem though. BOTH audio tracks are labeled English (verified in VLC Media Player on our laptop). Since both are labeled English, the episode plays the first track, which is actually Japanese just labeled wrong. WiiMC won't let me switch the audio tracks because they're labeled the same. >.< I've tried everything for this. Is there a way to rename the audio tracks so that it will work?

You can use mkvtoolnix to do it.

Thanks! Worked perfectly. Now we can finish watching the last five episodes.

(My wife really can't stand watching things that aren't in English because she has trouble keeping up with the subtitles.) This was a big help and I really appreciate it.
