Problem: I can mount few DVDs, however few DVDs are throwing following error while mounting. I could see sr0 at the end of lsblk output after inserting dvd into Rom.
1. Command, I have used is #mount /dev/sr0 /mnt/CD. Output of this cmd is -
# mount /dev/sr0 /mnt/hd/
mount: /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
2. Output of dmesg | tail
[ 3868.377303] EXT4-fs (sr0): unable to read superblock
[ 3868.440938] sr 1:0:0:0: [sr0]

3. Tried mounting with -t iso9660 or -t udf - did not work.
4. Installed regionset - did not work.
5. Tried to play DVD directly from mplayer DVD:// and other possible combinations - Did not work
Note: libraries like dvdread, dvdcss, dvdnav are already installed on laptop. I am using SONY Vaio. These DVDs are working fine on DVD players. Only few DVDs are giving these errors.
Could you please help me mounting Dvds? ( Although, I have been using linux distros for long time, I have switched to arch linux recently and really loved it.)

you don't use automount for DVD and removable devices ? ( most of desktop managements like KDE/Gnome provide this feature )
otherwise if the standard mount command doesn't work this may related to a damaged DVD surface, or an anti-copy protection ( this kind of protection can generate problems with DVD-Rom player, but not on a standard DVD player )
the regular command for mounting a DVD video on archlinux is :
mount -t iso9660 -o ro /dev/sr0 /mnt/media
you can try without specifying the format :
mount -o ro /dev/sr0 /mnt/media
