cannot enable playlist dispatch or MP3ReloadRequest directive

Hello,
I am currently fighting a number of mod_mp3 related problems.

1.  I cannot use directive "MP3DispatchAgent playlist".  When I enable
it, I get a message telling me my only options are "internal" and
"mysql".  I ran ./configure --with-mysql --with-playlist, and it said it
was building dispatch support for playlist and mysql in the ./configure
output.  Is there some trick to enabling the playlist dispatcher?

2.  MP3ReloadRequest directive.  Apache tells me it is an invalid
command.  This may relate to above.  

What I am trying to accomplish here is to have apache/mod_mp3 run off of
a playlist, which I can then change through a web interface.  With the
internal dispatch, it will run a smallish playlist, but if I re-write
the playlist, it still only streams the same songs.  

3.  If I run "internal dispatch" with large playlists (~3000 songs),
apache will segfault.  I have not tested how big a playlist I can make
before this happens.  With about 50 songs it works fine.  I have
recompiled PHP and mod_php without native mysql support, as suggested by
one of the warnings durning the install, but that did not help. 

4.  If I try to run with the "mysql" dispatch, apache will segfault in
the same way as in #3 above.  The database is built correctly, and even
populates with all my songs (~3000), but apache will not start.  

I will be happy, and able to continue with my little project if I can
get any of the above 4 problems resolved. 

Thanks in advance
Alex
