Men In Black BD backup failed

[jherron58]

I have been backing up my BDs, and most have gone smoothly. But Men In Black just won't go. I am attaching the debug log, in hope that someone understands it, and can tell me whether there is anything I can do about the failure.

The Blu Ray drive is a Samsung, newly purchased (October 2013) so I can do these backups. I am running an old Mac Pro with 12GB of RAM, many TB of drive space, and OS X 10.7.5.

Any ideas? Thanks in advance.
