Problem:

I am trying to play a bluray disk on my Sony Vaio Laptop running Ubuntu 12.04.2.
I have tried many tutorials on how to do this and actually I was able to play 1 scene once. But after reboot it stopped working again.

What I have tried:

I did try anything suggested in this question and also tried to manually mount the disk. Both failed. I can run some termina command when no blu-ray is in the drive:

$wodim --devices

wodim: Overview of accessible drives (1 found) :

$ sudo lshw -c disk

  *-cdrom

       capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram

       configuration: ansiversion=5 status=nodisc

A dmesg | tail returns me many of these error blocks when a disk is inserted:

[ 2172.584143] sr 4:0:0:0: [sr0] Unhandled sense code

[ 2172.584176] Buffer I/O error on device sr0, logical block 0

I found more on this issue in an archlinux and openSUSE forum but both questions did not help me. Without a disk in the drive all a dmesg | grep sr0 returns is:

[    1.345366] sr0: scsi3-mmc drive: 62x/62x writer dvd-ram cd/rw xa/form2 cdda tray

[    1.345556] sr 4:0:0:0: Attached scsi CD-ROM sr0

libdvdcss is installed. So are libbluray1, libbluray-dbg and libaacs0. I also used this guied to patch my KEYDB.cfg and my libaacs0.so

I also tried the lxBDPlayer without success.

Question

I've read that this problem might be the result of a broken drive or a broken disk. The disk is brand new and should be fine (I also checked it for scratches etc.) and since the drive successfully plays audio-cds and DVDs I don't see how the drive can be broken. Is there anything you can suggest me to try. Any guide or tutorial you know about how to run bluray on ubuntu that I might have not tried yet?

If you need further information feel free to ask.

Edit:

I just tried another bluray disk with the following result:

Running dmesg |grep sr0 returns still similar results:

$ dmesg |grep sr0

[    1.345366] sr0: scsi3-mmc drive: 62x/62x writer dvd-ram cd/rw xa/form2 cdda tray

The drive is now responding to e.g. lshw -c disk

  *-cdrom

I wonder why the name is /dev/cdrom and not /dev/dvd?
When I try to open the disk with VLC the following error pops up in the VLC console:

Blu-Ray error:

Path doesn't appear to be a bluray

Your input can't be opened:

VLC is unable to open the MRL 'bluray:///dev/cdrom'. Check the log for details.

I don't think that there is a problem mounting Read-Only. CD's (DVD's, etc) are "read-only" discs, so mounting them read-only makes sense.

When you said that you've tried lxBDPlayer, did you also load the extra plugin, and software that makes work?

to use lxbdplayer, you will need to download the following:

• The lxbdplayer itself. This package is a .deb for Ubuntu and
  Debian.


• The AACSKeys plugin for lxbdplayer.


• The MakeMKV package (this is the 64-bit version. To get the
  32-bit version, click here).


• The ShowKeys library (this is the 64-bit version. To get the
  32-bit version, click here).

To install the packages, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo dpkg -i lxbdplayer_0.2.1_all.deb lxbdaacs_0.2.1_all.deb makemkv_1.5.5b_amd64.deb libshowkeys_v1.5.5_amd64.deb

You might need to download a couple of dependencies, but otherwise the installation is small and quick.

Once the install is complete, import the decryption keys needed by typing in the following command:

bdkey-install

Note: You may need to have the drive’s firmware patched.
