Yes, details here, with links to the spec:

Currently the gstreamer0.10-fluendo-mpegmux doesn't correctly write
PTS, i've a quick hack which fixes it.

Yes, details here:
http://wiki.xiph.org/index.php/OggDirac

However, the ogg mapping is a right pain.  The granulepos isn't useful
(one ends up having to ignore it and decode part of the stream anyway
if you are to recreate PTS correctly)

A matroska mapping is also being worked on.

Details of mappings are on: http://www.diracvideo.org/wiki
