[Bug 16722] Re: The user should be presented a GUI to set the region code of his brand new DVD drive when trying to read a CSS crippled DVD (When needed)

[Rémi Denis-Courmont]

That is a super bad idea. Read errors can happen for various reasons,
including obviously defective disks, purposefully standard-violating
disks (unfortunately a lame but common practice to attempt to contain
DVD piracy). Advising the user to set region upon read error would a
time bomb. It will cause many many users to destroy their drives
accidentally.

Besides, your drive is supposed to be zoned when you buy it. I fail to
see how the media player is to be blamed.

Bug description:
  Since I bought my laptop, I couldn't read dvd. I never searched for a solution -
  until today.

  This was a brand new laptop and it never booted anything else than ubuntu. The
  region code for the DVD drive was not set and it seems the drive refused to read
  DVD for this reason.

  After installing and using regionset (in universe, I think), it now works. There
  was no user friendly error but just this in the syslog:

  Buffer I/O error on device hdc, logical block 1877480
  hdc: command error: status=0x51 { DriveReady SeekComplete Error }
  hdc: command error: error=0x50
  ide: failed opcode was 100
  end_request: I/O error, dev hdc, sector 15019848

  FWIW, I'm using xine to read dvd, but I suspect it's libdvdread that should
  handle this.

  
  Addtional suggestion for a solution (from the commenters)  : 

  - When the player (totem, vlc etc..) see that even if libdvdcss is
  present the decss fails:

  -- Regionset should be installed and the region/set times last retrieved.
  -- A nice Gui is presented with the worldmap of regions ( see http://en.wikipedia.org/wiki/DVD_region_code#Region_codes_and_countries)  and the user select his region.

  -- A Big warning should be displayed saying that this can be done only
  a limited number of times.

  -- Then regionset is called.

  -- Then the playback can be restarted only if the region of the DVD
  and the drive match.
