Public bug reported: I believe this is a duplicate of 304954 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/304954?comments=all), but apport will not let me add to that bug report for some reason.
Inserting a DVD+R that was burned on my DVD player/recorder from an old VHS home movie (absolutely no copy protection anywhere) results in the following kernel message, repeated many, many times: [185941.874746] sr 2:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [185941.874749] sr 2:0:0:0: [sr0] Sense Key : Illegal Request [current] [185941.874752] sr 2:0:0:0: [sr0] Add. Sense: Illegal mode for this track [185941.874756] sr 2:0:0:0: [sr0] CDB: Read(10): 28 00 00 00 00 00 00 00 01 00 [185941.874761] end_request: I/O error, dev sr0, sector 0 [186958.829588] lo: Disabled Privacy Extensions I can mount most video DVDs and data DVDs and CDs. The command 'sudo mount -t iso9660 /dev/dvdrw /mnt' results in the message: mount: block device /dev/sr0 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/sr0, missing codepage or helper program, or other error (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) In some cases useful info is found in syslog - try dmesg | tail or so and more of the same kernel messages. This happens with both of my DVD drives (NEC DVD RW ND-3550A and LITE-ON DVD SOHD-16P9S).
