I wrote the library in question (bdtools).  That code has been
superseded by current svn of the libbluray project. 
http://altair.videolan.org:4280/
The old codebase has some bugs that I haven't bothered to go back and fix.

Unfortunately this project was started with a closed svn and then the
project leader vanished.  So access to outsiders has been limited.  But
people that want access can get it by talking to j-b on irc #libbluray.

In the bdtools tarball, you'll find some notes I took while reverse
engineering the format.  There's a little more involved than simply
splicing together files. The beginning and end of a clip doesn't have to
coincide with the beginning and end of the file.  There are start and
end points defined in the playlist.  Though 99.9% of the time, simply
splicing the files will work.  The libbluray project has a bd_read
function that does all the proper splicing.
