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. -- Karmic: DVDs cannot be mounted in GNOME https://bugs.launchpad.net/bugs/438065 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to brasero in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
