I've experienced what looks like a very similar problem. I'm using k9copy as a front end for dvdauthor. I've noticed this only happens when backing up certain DVDs consistently; it appears to be modern DVDs with many tracks. The first titleset is authored, and the application crashes after the VOBUS is fixed.
I'm attaching a screenshot as well as a crash report, as it describes the complicated strucutre of the DVD well. ** Attachment added: "Screenshot" http://librarian.launchpad.net/6536975/Screenshot-k9copy.png -- dvdauthor crashes during k9copy copy https://launchpad.net/bugs/84048 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
