The proposed patch was - as far as I can see it - simply thought of as a
front-end to an eventual libbluray - whether this does aacs, bd+ and
everything (I mean, it's basically the setting up and the fill_buffer),
so not much labor is lost on the mplayer frontend side.

Unfortunately, I do get different results when playing from disc or the
unscrambled from hard disk (had to dump this all over again). If I have
the BDMV/index.bdmv present, mplayer crashes (after enumerating 2 indices

************** 2 *************

index: 1 duration: 00:23:11 chapters: 2

If I remove the file, I get

etc, which always plays index 0 (the 21:25 long feature).

If I run it on the original disc, the enumeration is a different one:

Here's the question: what format does the key.db file have? the same as
the current keydb.cfg for dumphd? or something else? or is my libaacs
simply too old?
