Voici mon fichier minidlna.conf :

# This is the configuration file for the MiniDLNA daemon, a DLNA/UPnP-AV media
# server.
#
# Unless otherwise noted, the commented out options show their default value.
#
# On Debian, you can also refer to the minidlna.conf(5) man page for
# documentation about this file.

# Specify the user name or uid to run as (root by default).
# On Debian system command line option (from /etc/default/minidlna) overrides this.
#user=root
#group=root

# Path to the directory you want scanned for media files.
#
# This option can be specified more than once if you want multiple directories
# scanned.
#
# If you want to restrict a media_dir to a specific content type, you can
# prepend the directory name with a letter representing the type (A, P or V),
# followed by a comma, as so:
#   * "A" for audio    (eg. media_dir=A,/var/lib/minidlna/music)
#   * "P" for pictures (eg. media_dir=P,/var/lib/minidlna/pictures)
#   * "V" for video    (eg. media_dir=V,/var/lib/minidlna/videos)
#   * "PV" for pictures and video (eg. media_dir=PV,/var/lib/minidlna/digital_camera)

# Type and minimum level of importance of messages to be logged.

# "metadata", "scanner", "ssdp" and "tivo".
#
# The levels are "off", "fatal", "error", "warn", "info" or "debug".
# "off" turns of logging entirely, "fatal" is the highest level of importance
# and "debug" the lowest.
#
# The types are comma-separated, followed by an equal sign ("="), followed by a
# level that applies to the preceding types. This can be repeated, separating

#   * "V" - "Video"
#   * Or, you can specify the ObjectID of your desired root container
#     (eg. 1$F for Music/Playlists)
# If you specify "B" and the client device is audio-only then "Music/Folders"
# will be used as root.

#enable_tivo=no

# Which method to use for registering in TiVo: 'bonjour' (default) or

Et voici mon fichier /etc/default/minidnla :

# Defaults for minidlna initscript
# sourced by /etc/init.d/minidlna
# installed at /etc/default/minidlna by the maintainer scripts

# These options can be set to modify the behavior of the minidlna init script.

# User and group the daemon should run as

GROUP="bernard-deb"

# Additional options that are passed to the daemon
# We pass -r option to do soft non-destructive rebuild on every start-up.
# If your systerm restarts often, you might want to remove this.
DAEMON_OPTS="-r"

Quelqu'un a-t-il une idée sur ce mystère ? 
Merci d'avance
