   Hi,
   I got 2 optical drives installed:
   - a DVD drive,
   - CD drive.

   I am unable to play neither CDs nor DVDs. For example here is the output of mplayer:
   

   tux@slitaz:~$ mplayer dvd://1
   MPlayer UNKNOWN-4.5.2 (C) 2000-2010 MPlayer Team
   MMX supported but disabled
   MMX2 supported but disabled
   3DNow supported but disabled
   3DNowExt supported but disabled
   
   Playing dvd://1.
   libdvdread: Using libdvdcss version 1.2.10 for DVD access
   libdvdread: Could not open /dev/dvd with libdvdcss.
   libdvdread: Can't open /dev/dvd for reading
   Couldn't open DVD device: /dev/dvd (No medium found)
   No stream found to handle url dvd://1
   
   Exiting... (End of file)
   tux@slitaz:~$

   => it indicates that something is wrong with /dev/... After investigating, I found that:

   tux@slitaz:~$ eject /dev/dvd
   Results in ejecting the wrong drive. Actually it opens the CD drive tray instead of the DVD tray.

   Here is where the /dev/dvd points to:
   

   tux@slitaz:~$ ls -l /dev/dvd
   lrwxrwxrwx    1 root     root             8 Dec 10 18:53 /dev/dvd -> /dev/hdd
   tux@slitaz:~$

   => this link to /dev/hdd looks strange to me.

   If you have any idea, let me know.
   Tkx

   Some news :-).

   The two drives are attached as:

   tux@slitaz:~$ wodim --devices
   wodim: Overview of accessible drives (2 found) :
   -------------------------------------------------------------------------
    0  dev='/dev/hdc'      rwrw-- : 'ASUS' 'DRW-1608P'
    1  dev='/dev/hdd'      rwrw-- : 'MATSHITA' 'DVD-ROM SR-8586'
   -------------------------------------------------------------------------
   tux@slitaz:~$

   But the /dev/dvd is linked to the wrong drive. I need to use /dev/hdc (ASUS one):

   tux@slitaz:~$ ls -l /dev/dvd
   lrwxrwxrwx    1 root     root             8 Dec 10 18:53 /dev/dvd -> /dev/hdd
   tux@slitaz:~$

   Does anyone knows how or in wich config file I can set to the correct drive mapping (dev/dvd -> dev/hdc).
   Thank for helping.

   Key Master

   #ln -sf /dev/hdc /dev/dvd

   FYI this is how SliTaz symlinks to drive.
   /etc/int.d/rcS :
   133 # Create /dev/cdrom if needed (symlink does not exist on LiveCD).
   134 # Also add /dev/cdrom to fstab if entry does not exist.
   135 if [ -n "$CDROM" ]; then
   136 DRIVE_NAME=${CDROM#/dev/}
   137 else
   138 DRIVE_NAME=$(fgrep -s "drive name" /proc/sys/dev/cdrom/info | cut -f 3)
   139 fi
   140 if [ -n "$DRIVE_NAME" -a ! "readlink /dev/cdrom" ]; then
   141 echo -n "Creating symlink : /dev/cdrom..."
   142 ln -s /dev/$DRIVE_NAME /dev/cdrom
   143 ln -s /dev/$DRIVE_NAME /dev/dvd
   144 status
   145 fi
