I have a collection of video files, mainly .mkv, which have more than one audio language. When played through Media Centre, it only plays the default language. If the default language is not English, I can not find an option to change it. In programs like VLC, I can change the language from the right-click menu whilst I watch the video.

Is there a way to choose the language? Or is there a way to change the default language / remove unwanted languages from .mkv files?

I am using Windows XP MCE 2005.
