Some time ago i already made basic support for MKV format in blender. 
Written in python.
Please see this file: http://195.205.38.39/mkv_support.blend.gz , there 
is simple example.

To see result please folow below description:
1. Render animation
2. Export chapters file by pressing Alt+P on script window
3. execute command: "mkvmerge -o ./test.mkv --chapters 
./mkv_support_chapters.xml ./test.avi" (be sure to have installed 
mkvtoolnix)
4. play your animation with mplayer and make sure to have correctly 
configured /etc/mplayer/input.conf - add or replace LEFT and RIGHT values:

LEFT seek_chapter -1
RIGHT seek_chapter +1

Now you can navigate your animation ..

> Ideas:
> For Subtitles support:
> - Use a new Marker in the timeline with a different color to define where
> a specific subtitle text will appear.
> - Have a new Window for subtitle creation that would have a list of all
> the markers (created on the timeline) on the left and a text field on the
> right that would contain the subtitle text.
> - Have a new subtitle strip on the sequencer that would have in its
> properties the ability to specify either an srt file or an internal
> subtitle set.

> For Chapters support:
> - Use a new Marker in the timeline with a different color to define each
> chapter.
> - Have a new Window for Chapters that would have a list of all the markers
> (created on the timeline) on the left and a text field on the right that

> For Multiple Audio files in MKV support:
> - Add to the Audio strip in the sequencer two new properties, one to say

> the final solution fast, instead of making me take longer to do it.
>
> Some ideas that come to my mind for the sequencer itself:
> - Media manager area with the contents preview of a folder always active
> that I can drag videos, audio, images directly into the sequencer
> - Snapping on the strips would be good
> - Some effects require an IPO curve, else they don't really do anything,
> this curve could be added by default for the effect.

> For now this is it.
