Discs in DVD Drive not being read

Solution 1:

Adding a entry in /etc/fstab may solve your issue, I was having issues using programs in wine that would not recognize my cdrom. In your case start by running:

sudo mkdir -v /media/cdrom0 ; sudo mkdir -v /media/cdrom1

This will create the future mount points for your cdrom drives. Then run this command which will edit in the proper lines in your fstab file:

 echo "# cdrom 0" | sudo tee -a /etc/fstab  
 echo "/dev/sr0 /media/cdrom/  auto ro,noauto,user,exec 0 0" | sudo tee -a /etc/fstab  
 echo "# cdrom 1" | sudo tee -a /etc/fstab 
 echo "/dev/sr0 /media/cdrom/ auto ro,noauto,user,exec 0 0" | sudo tee -a /etc/fstab

Then you will want to remount the file systems listed in fstab with this command:

sudo mount -a

Pop in a cd or dvd to see it this corrected the issue. If it did solve the issue there is some problem with automount. This is only a workaround for a bigger problem.

Solution 2:

Is it one specific DVD or all DVDs?

If it's all DVDs: You should also check the regionset in terminal type, sudo apt-get install regionset and then sudo regionset. And make sure the region code of the drive matches your region code. (This happened to me a couple of times randomly...)

If it's one specific DVD: Have you remembered to install libdvdread4 (if it's an encrypted DVD)?
