I'd like to re-open this bug. I'm reproducing it on Ubuntu Gnome 13.04 Raring 64 bit. Totally reproducible but this is what you initially observe VLC stops playing a DVD about an hour into the film with the error Playback failure: DVDRead could not read 0/4 blocks at 0x200b8b.
If you look in syslog you see that it is because the player (VLC in this case but actually ALL players do the same) has tried to read past the last block in the DVD Nov 1 23:03:23 aspire kernel: [ 3255.571794] sr 5:0:0:0: [sr0] Nov 1 23:03:23 aspire kernel: [ 3255.571795] Sense Key : Not Ready [deferred] Nov 1 23:03:23 aspire kernel: [ 3255.571799] sr 5:0:0:0: [sr0] Nov 1 23:03:23 aspire kernel: [ 3255.571802] Add.

Here is how to reproduce it 1) Reboot Linux 2) Put in a DVD that is quite short. Mine is called RORY" 3) Navigate to it with the file explorer. The DVD is correctly labled RORY on the left. 4) If you press <control>+L you can see it has been mounted to /media/andrew/RORY 5) Press the eject button ON THE DVD PLAYER 6) Take out the DVD and put in another DVD. Mine is called OCEANS_TWELVE 7) Close the DVD tray and navigate to it with file explorer. The DVD is correctly labled OCEANS_TWELVE on the left. BUT 8) If you press <control>+L you can see it IS STILL MOUNTED AT /media/andrew/RORY 9) Try to play with ANY dvd player and skip to near the end of the DVD. If the DVD you have in is longer than the DVD you ejected it will crash WORKAROUND Repeat steps 1 to 9 above but in step 5 press the eject button in the file explorer. The DVD gets properly unmounted and when you put in the new DVD the file label and mount point are the same. When you play the DVD it works properly. The reason people are reporting that rebooting works is because when you reboot, the DVD you are trying to play is the first DVD that Linux sees and it gets mounted properly THIS HAS BEEN DRIVING ME MAD FOR MONTHS. EVERY TIME WE WATCH A DVD IT STOPS AFTER PLAYING!! Now I realise all I have to do is properly unmount it and remount it and everything is hunky dory. So I think the only fix required is to make sure that DVDs get properly UNMOUNTED when you hard eject using the DVD player eject button. Being a noob I have absolutely NO idea how to do that. Fixes anyone? Anyone find that my steps above DON'T work please make sure that the first DVD is shorter than the second one otherwise you won't experience the same behaviour. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/404472 Title: DVD - 'attempt to access beyond end of device' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/404472/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
