I was trying to a dvd copy with dvd shrink. It failed with CRC Error. Then I tried it with DVD Decryptor ending with Input/Output Error.

Solution:

1. Use Ubuntu
2. $ sudo apt-get install gddrescue
3. $ vlc
   1. open the disc
   2. play and pause. # by this disk is authorized to access in the dvd player hardware level, which is a part of copy protection.
4. $ sudo ddrescue -d /dev/sr0 THA_DAA_ALS.iso backup.logfile.
   backup.logfile is just for a log.

   GNU ddrescue 1.22

                                 time since last successful read:          0s
   Copying non-tried blocks... Pass 1 (forwards)
   
   	

5. Enjoy the .iso!

• How to use ddrescue

I have tried several DVD Rippers in vain. That is how I switched to Ubuntu.

• On Windows.
  • DVD Shrink
  • DVD Decrypter
  • HandBrake
• On Ubuntu
  • dd (fail!)
  • ddrescue (Success!)

The points:

• The underlying cause of the issue is that your DVD drive is working against you. As per Wikipedia:
  

  However, if the drive detects a disc that has been compiled with CSS, it denies access to logical blocks that are marked as copyrighted (§6.15.3[2]). The player has to execute an authentication handshake first (§4.10.2.2[2]).
  

  So it's not just that you will get encrypted data that can't be played if you read the DVD; the drive won't send back the bits unless some program on your machine has authenticated itself to the drive.
• ll I need to do to rip a DVD using dd (my preferred method) is to first open the subject DVD using SMPlayer and then pause the playback. While said SMPlayer window is open, I can then dd-rip the subject DVD to my heart's content!
