Comment 15 for bug 788322

After some digging and experimenting I have found the following which I hope may of help to other people in a similar predicament...

Problem caused by cdrecord (http://cdrecord.berlios.de/) licensing issues and past feuds which result in cdrkit (http://www.cdrkit.org/) being installed on system (Debian, Ubuntu, Suse, etc) and used in place of actual cdrecord binaries.

cdrkit binaries based on old and buggy code.

k3b patched to detect cdrkit installation and use growisofs instead - https://git.reviewboard.kde.org/r/101208/. In referenced bugs growisofs seems to have an issue closing the BD-R session resulting in the last file burnt to the disc being faulty and the disc left open ("Appendable: yes" in k3b after burning).

Solution is to install cdrecord. Removal of cdrkit isn't required as k3b will detect cdrecord from default install path of /opt/schily/.

For installation instructions on Debian-based O/S see: http://ubuntuforums.org/showpost.php?p=5552555&postcount=5

Note that you can stop at 'sudo make install' in the above and k3b will find cdrecord, no adjusting with symlinks in /usr/bin is required.

Apparently as detailed in http://forum.kde.org/viewtopic.php?f=153&t=85895&start=15#p165603 - setting k3b to "No Multisession" will cause it to use cdrecord instead of growisofs.

Have tested the above on Debian Wheezy.

Good luck - Ben Whorwood (mube.co.uk)
