hi void
today i have a question about mkv-menu-dvd-style-support.
mkv-menu is a "normal" feature of mkv.
i have tested DVDMenuxtractor: its generated me a menu.xml (chapters) and a info.xml (segmentinfo). this files can you mux with mkvmerge without issues, but there is no Splitter that can handle this mkv-menu-file.
maybe you have time und lust to implement this feature.
here you find a post with the files in the attachements. http://forum.gleitz.info/showthread.php?34646-Men%FC-und-mkv&p=438051&viewfull=1#post438051
