I just updated to SVN.
>>> info = kaa.metadata.parse('/media/MEDIA-7A/Air Force One/Air Force One.mkv' )
>>> print info.audio[1].language
German
>>> print info.audio[0].language
None
>>> info = kaa.metadata.parse('/home/dan/Desktop/Air Force One (1).mkv' )
>>> print info.audio[0].language
Undetermined
>>> print info.audio[1].language
German
So the undetermined change works, however the original (which was set
to eng when packaged with mmg) still shows None.

I was surprised when I saw this as well. It didn't make sense to omit
the eng language code, seems like that reasoning should have been
thrown out when we all moved to UTF-8 ;-)

But with the und change at least I can work around it, and this is
true to the format at least.

Thanks for the quick response and update though!
