Unfortunately, I had no luck with the blanks. All 5 functioned not end, even though I've only burned an extra 2.4 times speed. On Image It was not because this has a DVD + R DL blank work on first time. Some of the burned DVDs were not read, in part, she could recognize the PC after prolonged reading. My burner is a LG GH22LS40.
I used since the same from Verbatim DVD + R DL and had no problems.
