The media is made by Ritek (Made in Taiwan).  Thanks to Conrexx Technology B.V. (The Netherlands) for sending us this media.

Testing procedure: We created an ISO Image of the largest DVD-Video disc we had (Nemo, 7.91 GB (8.495.888.384 bytes)) using DVD-Decrypter. Then we wrote this image file using Nero Burning ROM 6. Below are the results:

Mitsubishi Kagaku Media

Traxdata media

The LG GSA-5160D used 44 minutes and 25 seconds for writing the Mitsubishi Kagaku media at 2.4x and 44 minutes and 41 seconds for writing the Traxdata media at 2.4x. Let us take a look at the K-Probe result:

The KProbe result is good/ok.

The result is ok, and we can see that the 2^nd layer got higher PI. And now it's time to take a look at some reading tests with various DVD-Writers.

First we will try to read the discs back in the LG GSA-5160D drive:

Mitsubishi Kagaku Media

Traxdata media

As we could see, the LG GSA-5160D had no problems reading the discs. Let us try some other drives to read the Dual Layer discs:

Mitsubishi Kagaku Media

Traxdata media

The Plextor DVDR PX-712A shows a perfect reading curve on both media.

Mitsubishi Kagaku Media

Traxdata media

The Lite-on SOHW-1633S also shows a perfect reading curve on both media.

Traxdata media

The same goes for the LG GSA-4163B

Let's compare the LG GSA-5160D with other DL capable drives.

* Verbatim DVD+R9 DL
** Philips DVD+R9 DL
*** Traxdata DVD+R9 DL

Standalone DVD-Player compatibility:

We only have 3 standalone DVD-Players available and 1 standalone DVD+R/W recorder to test the DVD+R9 DL media (Book Type: DVD-ROM).

• Aiwa DVD Player XD-DV370
• Medion DVD/Div-X Player MD7457
• Red Star DVD-Player 230G
• Mustek R100A DVD+R/W Recorder

Compatibility results:

All 4 standalone devices played the DVD+R9 DL burned Medias.

Summary: Excellent/good write quality and standalone compatibility results.

Before we round off this review, let us run the drive through some advanced tests at next page…
