Nero CD-DVD Speed: Basic DVD Tests

The second group of tests is about DVD formats. We used six discs to get a full picture: a DVD-ROM with a video movie and its copies made on DVD-R (Digitex), DVD-RW (TDK), DVD+R (Fujifilm), and DVD+RW (Verbatim) discs. We also used a dual-layer DVD+R from RIDATA with movie files.

Two notes about the following diagrams: some drives couldn’t process the DVD-R disc from the beginning and two drives read the top layer of the DVD+R DL disc normally but could not complete the test when they transitioned to the other layer.
