If this is reproducible, then drive and/or media are at the edge of failure. Did you already try with preventing automatic formatting of the BD-R by -use-the-force-luke=spare=none ? To my (personal, subjective, questionable) experience the write quality is better without Defect Management (e.g. with growisofs on unformatted BD-R). I conclude this from the fact that i could write and read BD-RE and BD-R without Defect Management which nearly always failed if it was enabled. I am thrifty and thus normally use BD-RE for experiments. But i already had occasions where BD-R were unreliable. In the end, either the poorly compatible media were used up or the drive dropped dead completely. I had to replace 1 Pioneer and 1 LG during the last 8 years of BD burning. Have a nice day :) Thomas
