I think it would be great to have the support of segment link for matroska,
a guy on IRC (Arneb) made this :
http://www.ps-auxw.de/ordered/
"<ArneB> http://www.ps-auxw.de/ordered/ - FWIW, I made two ordered chapter
samples. One with single file, one with three linked files.
<ArneB> First edition should play "Part A", then "Part B" twice. Second
should play "Part A version 2", then "Part B" twice"
Also you can find here an example of the chapters.xml :

What for ? To gain disk space, example :
An episode of One Piece in HD 720 = 500 mo for an episode of 23 min
The opening = 3 min
This opening is the same since the 284 and now the last episod was the 309
=> (500/23) x 3 = 65
=> 65 x ( 309-284) = 1625 mo
I let you imagine for HD 1080
It also be useful for videos with part1 and part2.
Thanks in advance
