[Bacula-users] Backing up to DVD

I am running into problems with multi-volume DVD backups with Bacula. I have an external USB 2.0 DVD writer which seems to work fine standalone; however, when I attempt to carry out a backup via Bacula it fails randomly with Input / Output errors.

I have attempted backups several times with several different DVD media. I can confirm that it fails every time on the first volume. It writes between 1 and 5 parts before dieing with an Input / Output error. I all cases it is caused by growisofs.

Any ideas?

Bacula version: 2.4.2 (source rpms)
dvd+rw-tools version: 7.1 (compiled from source)

Storage daemon configuration:

Device {
Name = "DVDStorage";
Media Type = DVDStor;
Archive Device = /dev/sr0;
LabelMedia = yes;            # lets Bacula label unlabeled media
Random Access = Yes;
AutomaticMount = yes;        # when device opened, read it
RemovableMedia = yes;
AlwaysOpen = no;
MaximumPartSize = 800M;
RequiresMount = yes;
MountPoint = /mnt/bacula-dvd;
MountCommand = "/bin/mount.sh %a";
UnmountCommand = "/bin/umount %a";
SpoolDirectory = "/var/spool/bacula";
WritePartCommand = "/usr/lib/bacula/dvd-handler %a write %e %v"
FreeSpaceCommand = "/usr/lib/bacula/dvd-handler %a free"
}

Bacula directory configuration:

Storage {
Name = DVDStorage
Address = [REMOVED]
SDPort = 9103
Password = [REMOVED]
Device = DVDStorage
Media Type = DVDStor
}

Pool {
Name = MonthlyDVD-1

Maximum Volume Jobs = 1
Maximum Volume Bytes = 4294967296
AutoPrune = yes
Volume Retention = 3 weeks
Recycle Oldest Volume = yes
Label Format = Monthly-DVD1-VOL

}
