FC6 not reading DVDs

[Jeff Mutonho]

My FC6   machine is failing to read DVDs.I've tried all sorts ,
including originals , without luck.However CDs are working fine.
When I try to mount the drive with a DVD in it , I get the message
"unable to mount media. there is probably no media in the drive"
and yet , when i eject the DVD and insert a CD instead , all works
fine.This problem only started after the upgrade from FC5 to FC6

I have seen a problem occasionally on my machine, though usually after
using it once. I have also ejected a DVD, inserted another, only to find
that FC6 still thinks the original disc is in the machine (volume label
is the same and I see the same old files in the nautilus window.

I have rebooted, and manually unmounted the disc to resolve this before
and have not seen it again for some time so I don't know if it will
recur (I don't often watch DVDs) but you could try a 'umount /dev/hdd'
or whatever your drive is.  You might give it a '-l' (lazy) also as I
find this helps a lot in the case of difficult umounts.

My /etc/fstab looks as follows :
LABEL=/                 /                       ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
tmpfs                   /dev/shm                tmpfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0

LABEL=SWAP-hdc3         swap                    swap    defaults        0 0


and /etc/sysconfig/hwconf

class: CDROM
bus: IDE
detached: 0
device: hdb
desc: "DVD-RW IDE1108"


What else can I look for?

If you look in /var/log/messages, do you see any odd messages when you try 
and mount the dvd?

If you try and mount the dvd using a mount command, does it dump odd 
errors to the console or the log?

What does "hdparm /dev/hdb" return?

Ok perhaps its the midnight old getting to me.This "mount -r -t
iso9660 /dev/dvdrw /media"
worked.I was using the "mount -t udf /dev/dvdrw /media' and mounting
was failing .
But now the question is why are CDs automounted and DVDs not?What
should I do to get the DVD automounted .I don't wannt type "mount -r
-t iso9660 /dev/dvdrw /media" everytime I want load a DVD.

You should not mount directly on /media, but instead off of a
directory off of /media. You may want to use

gnome-mount -d /dev/dvdrw

instead. It will create a directory off of /media, and mount the DVD
there.  The name will be based on the label of the DVD. I am not
sure why your DVD's are not mounted - it might be because they are
UDF. I have ISO9660 data DVD's, and they mount fine, but I do not
have any UDF format disks to try.

How are you trying to mount the DVD's? If you are using the
graphical desktop, such as Gnome or KDE, and you have not turned off
auto-mounting, then data DVD's should show up as a directory off of
/media. With video DVD's, you normally use a program such mplayer to
play them. For encrypted DVD's (most commercial DVD's), you need to
add the proper codex  - usualy from one of hte non-redhat repo's.
There have been long threads on why they are not included in the
default install...
