As usual we may say - the Ritek double layer media is simply not good enough. We have seen this so many times before L

The K-Probe result seems fine, but it failed to read back. Looks like there is still room for improvements.

The disc is at least fully readable unlike the Ricoh and Ritek double layer media. This media should not cause you any problems under normal use.

The Verbatim and Prodisc Double Layer disc worked fine in our standalone player, as long as we set the book type to DVD-ROM.

Seems good, but let us do some additional tests.
As we could see here the book type of the DVD-R DL disc is DVD-R. We tested the disc in several drives, and some could not read the disc; Toshiba SD-R5372 could not detect the disc and NEC ND-3500A recognized the disc as an empty 4Gb DVD-R disc! It worked fine in all drives that support the DVD-R DL format of course, but otherwise it seems to be a hit and miss.
Our pretty new Denver DVD-Player was only able to play the first layer of the disc.
Summary: Verbatim DVD+R DL works excellent with this drive, but most of the others discs have some problems - this could be due to lower disc quality and not due to a problem with the drive. DVD-R DL works fine as well, except that the compatibility of the DVD-R DL format seems to be inferior compared to the DVD+R DL format.
Before we complete this review, let us run the drive through some advanced tests at next page…
