DVD+R/-R Double Layer writing speed and compatibility:

The LG GSA-4167B supports the DVD+R DL/-R DL standard for writing Double Layer/Dual Layer discs with a size around 8.5 GB at a writing speed of 6x/4x. Let us first take a look at the media's we will use:

Let's find the manufacturer and media information too, for this we will use CD-Speed:

This media is manufactured by Mitsubishi Kagaku Media. Thanks to Verbatim (D) for sending us this media.

The media is made by Ricoh Co. Ltd. (Made in Taiwan).  Thanks to Ricoh Europe (Germany) for sending us this media.

The Traxdata media is manufactured by RITEK. Thanks to Conrexx (NL) for sending us this media.

Testing procedure:
We created an ISO Image from a pre-authored DVD-Video compliant file set, with a total on-disc size of 8103 MB. We then wrote this image file using Nero Burning ROM 6. Below are the results:

Ricoh Media

Nero reported a successful burn with the Ricoh media in 44 minutes 48 seconds.

Traxdata media

Nero once again reported a successful burn with the Traxdata media in 44 minutes 19 seconds

Verbatim media

Nero once again completed the burn successfully with the Verbatim media in 28 minutes and 49 seconds. According to the total writing time, there must be an slowdown at 4x since the writing time is to high for 6x.

Let us take a look at the K-Probe results:

High PI errors in the beginning and at the end of the disk.

Very high PI and PIF on the first layer of the disk, but the disk were still readable though without any noticeable problems.

The PI errors are higher on the second layer, but overall the result is good.

* As mentioned before, this media got properly a slowdown to 4x during the burn, since the total writing time is to high for 6x.

Let's compare the LG GSA-4167B results with some other DL capable drives.

DVD-R DL

As mentioned in the beginning of this page, the LG GSA-4167B supports the DVD-R DL standard at 4x. Let us first take a look at the media we will use:

Let's find the manufacturer and media information too, for this we will use CD-Speed:

This media is manufactured by Mitsubishi Kagaku Media. Thanks to Verbatim for sending us this media.

Again, we used Nero Burning Rom 6 to write the DVD Image:

The LG GSA-4167B used 27 minutes and 25 seconds to write the Verbatim DVD-R DL 4x media at 4x.

Overall this media was burned with very good quality.

Standalone DVD-Player compatibility:

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

• 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 DVD Standalone devices played the LG GSA-4167B burned DVD+R DL medias. But only one DVD Standalone devices would play the DVD-R DL media.

Summary: Very good quality on the DVD-R DL media, but the quality on some DVD+R DL media could have been better. The DVD standalone compatibility results, for the DVD+R DL media is very good.

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