Amazon as always 5 star, on time! 1 blank for testing packed with video, no problems with playback. Disk deleted, now burned with MP3, also no problem. Deleted disk back, burned backup on Restore with this disk without errors. I can not estimate how often I can do this with only one disk, DVD-RW DL, it went only 2 times delete and describe, then there was something for the shredder. Therefore I a buy recommendation.
