DVD+R Double Layer writing speed and quality:

The Memorex MRX-525GE supports the DVD+R DL standard for writing Double Layer discs with a size around 8.5 GB at a writing speed of 8x.

Testing procedure:

We created an ISO Image from a pre-authored DVD-Video compliant file set, with a total on-disc size of nearly 8.5GB. We then wrote this image file using Nero Burning ROM 7. Below are the results:

Verbatim 8X DVD+R DL

A high spike in the Scan, transfer rate curve is smooth.

Verbatim 2.4X DVD+R DL

The MRX-525GE burned this disc at 6X with good scan and a smooth Transfer Rate curve.

DVD-R Dual Layer writing speed and quality:    

The Memorex MRX-525GE supports the DVD-R DL standard for writing Dual Layer discs with a size around 8.5 GB at a writing speed of 8X.

Testing procedure:  We created an ISO Image from a pre-authored DVD-Vide compliant file set, with a total on-disc-size of nearly 8.5 GB.  We then wrote this image file using Nero CD-DVD Speed.  Below are the results of our tests:

High PIE levels, however PIF is low; read back test shows two slow downs in the 2^nd layer.

Good results on this burn with the MRX-525GE.

Standalone DVD-Player compatibility:

We only have 2 standalone DVD-Players available to test the DVD+R DL media (Book Type: DVD-ROM) and the DVD-R DL media (Book Type: DVD-R):

·         Panasonic DVD-S29S

·         Insignia TV/DVD Combination Player

Compatibility results: 

All brand of DVD+R DL play nicely in both players. However, the Verbatim DVD-R DL froze at the layer break in Insignia Combination Player. We would like to mention, that the compatibility issue with standalone DVD Players and the DVD-R DL media format is also caused by incompatibilities with the standalone devices used in this review, as we know the DVD-R DL format has inferior compatibility compared to DVD+R DL especially with older standalone player.

Summary:  The Memorex MRX-525GE burns DVD+R/-R DL with good results except our newly acquired DVD-R DL 8x produced high PIE along with slow downs in the TRT.
