Home - Did not work on ANY blu-ray burner

Perhaps I just got a bad batch but not ONE disc out of these ten would be recognized, let alone burn, in ANY of my 3 computer systems with fairly recent blu-ray burners. The drives spunked around a bit and then acted like there was no disc in the drive on 2 desktops and 1 laptop all equipped with 8x bd-r burners. I have had great success with optical quantum single layer bd-r but wanted to make backups of a lot of movies I own that are 30 to 50 gigs and thought this would be the answer.No go.
