Ok I have tried on my own a littlebit: 

plugins () {
ls $PLUGIN_CONFS 2> /dev/null > /dev/null
if test -e 0 ; then
for plugin in $(basename `ls $PLUGIN_CONFS/*.conf`) ; do {
if test -e $LIBDIR/libvdr-$plugin.so*; then 
for option in `sed -e's/#.*//' -e'/^ *$/d' -e's/"/\\"/g' 
"$PLUGIN_CONFS/$plugin"`; do
                   options="$options --$option"
  done;

  PLUGINS="$PLUGINS -P\"${plugin%%.conf} $options\""
fi
  }
done
fi
}


with f.i. mp3.conf :
--------------------------
#mp3 (0.8.0) - A versatile audio player
#
# mount=CMD    use CMD to mount/unmount/eject mp3 sources 
#  (default: mount.sh)
#
# network=CMD  execute CMD before & after network access        
#  (default: none)
#
# cddb=DIR     search CDDB files in DIR 
#   (default: /var/lib/cddb)

#network=/usr/local/bin/vdrinternet
-----------------------------------


If someone sees a possible problem here it would be nice to notify me,  
i can too just use Klaus style, i just thought it is more in .conf file 
style ;). 

comments are welcome

Steffen
