I just last night cut a dual layer DVD with growisofs. It appears to have cut fine. When growisofs stops in the middle like that, it's often caused by media defects. Have you tried another disk? Another possibility is that the drive is worn out. DVD writers have a limited lifespan largely measured by the number of disks they cut.
