I encountered a DVD plack back issue with some commercial DVDs. I can rule out hardware issues as the DVDs can be blacked using the same DVD device on my Ubuntu laptop.
I dmesg, I see the IO error normal to copy protected DVDs. Before I updated OSMC, I saw the “Add. Sense: Read of scrambled sector without authentication” error message. After updating to KODI 16 beta, it turned to the following error. But I think this is essentially the same:
dmesg:

KODI produces the following output:

Also the “Play Disc” button comes up. But Kodi is not able to start the playback. As said, I’m able to watch the disk using vlc on my laptop. Any hint is welcome!
Hello,
I stumbled across this problem recently, too, on Raspberry Pi 2. I’m quite sure the same discs worked sometime ago (before the December update?).
Root cause seems to be udev etc. medium detection. The problematic DVDs will not get automounted by the udisks system. The default command from /etc/udisks-glue.conf is executed because no filesystem is detected.
After inserting a problematic disc, “udevadm test-builtin blkid /sys/class/block/sr0” yields no contents after “probe /dev/sr0 raid offset=0”. Kernel log:
Jan 03 18:29:05 osmc kernel: sr 3:0:0:0: [sr0] UNKNOWN(0x2003) Result: hostbyte= Jan 03 18:29:05 osmc kernel: sr 3:0:0:0: [sr0] Sense Key : 0x5 [current] Jan 03 18:29:05 osmc kernel: sr 3:0:0:0: [sr0] ASC=0x6f ASCQ=0x3 Jan 03 18:29:05 osmc kernel: sr 3:0:0:0: [sr0] CDB: opcode=0x28 28 00 00 00 04 00 00 00 02 00 Jan 03 18:29:05 osmc kernel: blk_update_request: I/O error, dev sr0, sector 4096 Jan 03 18:29:05 osmc kernel: Buffer I/O error on dev sr0, logical block 512, async page read
With a working one, “udevadm test-builtin blkid /sys/class/block/sr0”: probe /dev/sr0 raid offset=0 ID_FS_PUBLISHER_ID=WARNER_HOME_VIDEO ID_FS_UUID=2003-01-29-18-27-45-00 ID_FS_UUID_ENC=2003-01-29-18-27-45-00 ID_FS_LABEL=SOME_LABEL ID_FS_LABEL_ENC=SOME_LABEL ID_FS_TYPE=udf ID_FS_USAGE=filesystem
and no kernel messages.
BUT: I can manually mount the disc and then watch the DVD within kodi without problems. So, as a workaround I put a script that executes udisks --mount /dev/sr0 together with PlayDVD() on a key.
