I have similar problem. I am assuming it is same as this bug because the messages in dmesg led me here (via Google Search). I initially thought the drive was faulty but it is not the case.
What works:
Audio CD, Video CD, non-CSS-encrypted DVD, all mount fine.
What doesn't work:
CSS-encrypted DVD, irrespective of region code.
Workaround tried:
I tried removing (lib)brasero*. That doesn't help.
I tried installing mainline kernel from the PPA for date 2 October. Even that doesn't help.
Please let me know if there is any more information needed.
