PI/PO quality results

The following screenshots present the PI/PO results for various DVD-/+R and DVD-/+RW media, recorded with the Toshiba SD-R 5272 at the maximum allowed speed.

The software used for the measurements was KProbe v1.1.28, the ECC was set to 8 and the reading drive was the LiteOn LDW-811S. The specific methodology is very dependable on the drive used as a reader, while the reliability of the PI/PO provided output is not also technically confirmed. Thus as a result, we cannot safely come up with conclusive results, although we do make a comparison of the drive's behavior when using various DVD recordable/rewritable media.

The recording discs used are presented below, coming with details about each disc type.
