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 sysfs /sys sysfs 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?

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...

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.
