I have more or less nailed the format of an AOB - it is similar enough
to a VOB for mplayer to recognise it (both are MPEG Program Streams with
LPCM audio stored as a private stream).  But an LPCM private stream in
an AOB file is not the same as the one in a VOB - the LPCM headers are

AFAIK, there are no AOB demuxers available at the moment, but I'm
planning to write one.  Keep an eye on my project at
http://dvd-audio.sourceforge.net  I've already partially document the
contents of the AUDIO_TS directory.

Yes, it's not possible to "author" a DVD containing WAV files.  But that
I mean control the order the WAVs are played back in, decide if there
should or should not be gaps between tracks, offer alternative playlists
for the same content etc etc.
