[Bug 44233] Re: mount udf dvd fails, possible wrong fstab entry

[Mger Zero]

I'm using 10.04 Lucid; other ubuntu versions are probably similar.
The temp fix may or may not work for all udf types.

The bug seems to be caused by auto-mount.
Auto-mount tries to mount udf dvd as type udf.
However, udf dvd-video should be mounted as type iso9660.

A temp fix is to manually mount the dvd drive.

1. Make a new folder to use as a mount point, or use any existing empty folder.
  sudo mkdir /media/dvd1
  
2. List your dvd drives with this command:  
  wodim --devices
  
3. Look for "dev=".
  Your dvd drive is likely to be /dev/scd0 
  The shortcut /dev/dvd may also work.

4. Unmount the folder, just in case.
  sudo umount /media/dvd1
  
5. Mount dvd drive.
  sudo mount -t iso9660 /dev/dvd  /media/dvd1

or if your device is  /dev/scd0
  sudo mount -t iso9660 /dev/scd0   /media/dvd1
  
If you use vlc media player to play udf dvd-video, you may need to disable "DVD menus".
In vlc, Media > Open Disc > check "No DVD menus"
  Disc device = /media/dvd1

vlc command line:
vlc dvdsimple:///media/dvd1

All commands used listed:
---------------------------
sudo mkdir /media/dvd1
wodim --devices
sudo umount /media/dvd1
sudo mount -t iso9660 /dev/dvd  /media/dvd1
vlc dvdsimple:///media/dvd1


If you are mounting an udf iso, try
  sudo mount -t iso9660 -o loop /pathToIso/filename.iso  /media/dvd1

Title:
  mount udf dvd fails, possible wrong fstab entry

Status in The Util-Linux-ng Set of Utilities:
  Fix Released
Status in “linux” package in Ubuntu:
  Invalid
Status in “util-linux” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: mount

  I cannot mount DVDs with udf file system. iso9660 cdroms and dvds work
  okay.

  My fstab has the entry:
  /dev/hdc        /media/cdrom0   udf,iso9660 user,noauto     0       0

  When trying to mount a udf dvd, I get the message:
  wrong fs type, bad option, bad superblock on /dev/hdc,
         missing codepage or other error

  /var/log/messages shows:
  Unable to identify CD-ROM format.

  Changing the fstype in /etc/fstab from "udf,iso9660" to "auto", makes
  everything work fine.

  Is the fstype "udf,iso9660" supposed to work and the problem is in
  "mount"? Or is this correct that one cannot use mutliple fstypes in
  fstab? Then the problem is in the program which created fstab at
  installaion (installed with dapper flight 5 cdrom)

  Best,
  Daniel
