In MKV files with multiple audio tracks of different langauges, Perian (QuickTime?) seems to use the system language preference order to determine default tracks, rather than setting the enabled tracks according to defaults explicitly specified in the MKV file. This is very annoying, as there's no way to display a given language by default (if you don't want whatever your preferred language in OS X is to be the default).
Even enabling the first track encountered of a given type would be acceptible, rather than the horribly broken behavior Perian currently exhibits. As an English speaker who watches lots of non-English MKV videos, I have no way of watching in the media's native language in Front Row, other than re-muxing the file to exclude English tracks.
If example files, or anything else is needed, please let me know.
