The Verbatim DVD + R discs are not in vain several times become test winner in several tests. They can be up to 16 times to describe and I had a Sony burner so far only 2 losses. Over the last months and years, not a single blank has not be able to play and they have not for nothing a very good reputation. Also known are completely satisfied with these blanks. I am amazed that the blanks seem really scratch- me. See Everyday use blanks with "Scratch Resistant" significantly better than without. A bad blank sneaks everywhere times, but I've learned that with some blanks simply can not work well together some burners. So it is not always on the blank. All in all a good blank with high data security.
