Multiple SRT in matroska

[bokonon]

Is it possible for an MKV container to output two srt files simultaneously? Basically a feature like PowerDVD which offeres primary and secondary subtitles (primary are displayed at the bottome of the screen, secondary at the top). This would be really useful for things like hardcoded text in parts of films / director's commentary in foreign language film where u might want to be reading the dialogue as well as the translation of the director's commentary.

It's not theoretically impossible (it doesn't really require anything special from the containers side), but I'm not aware of any players/renderers that support this right now.

KMP can do that but the second subtitle should be loaded manually.
