DVD+R Double Layer writing speed and compatibility:

The Memorex DVD+/-RWN16 D2 supports the DVD+R9 DL standard for writing Double Layer discs with a size of 8.5 GB, at a writing speed of 4x. First let us take a look at the DVD+R DL writing technique used by the drive.

We burned a Verbatim and Memorex Double Layer discs using Nero 6. Here we wrote the Verbatim Double Layer disc as a DVD ISO image in Nero 6 using the Disc-at-once writing method: 

Verbatim (MKM001) DVD+R DL written at 4x.

The drive wrote 8132MB in 26 minutes and 43 seconds.

We also tested burning with DVD Decrypter on a Fujifilm DVD+R DL disc:

 
Fujifilm (RICOHJPND00) DVD+R DL written at 2.4x. Total writing time is 43:35.

Next we will examine the writing quality on these DVD+R DL discs.

DVD+R DL Write quality:

Excellent results! Kprobe results look very good and the transfer rate reading curve is smooth on multiple drives!

Good results also on this Memorex DVD+R DL media. There are a few PIF spikes that showed up, but the appearance of these does not affect disc readability.

More nice results with Fujifilm DVD+R DL media! The PI levels spike near the end of the scan, but it is still an okay result.

Let's compare the Memorex DVD+/-RWN16 D2 with other DVD+R DL capable drives.

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

The Memorex DVD+/-RWN16 D2 performed very well compared to the competition. It was faster than all of the other 4x DVD+R DL drives and it produced one of the best quality results that we have seen.

Standalone DVD-Player compatibility:

The Memorex DVD+/-RWN16 D2 automatically sets a Book Type of DVD-ROM on DVD+R DL discs, which should help to ensure maximum compatibility with standalone devices. We tested with two different standalone DVD players to check the playback abilities of our DVD+R DL discs. The players we tested with are:

⋅        Philips DVP-642
⋅        Koss KD365

All of the Double Layer discs were recognized and played without issue on our standalone devices.

DVD+R9 DL Summary: The Double Layer performance of this drive is impressive. 4x burning on Verbatim DVD+R DL media is very swift and done with excellent quality. Memorex and Fujifilm DVD+R DL media are also written with good quality. We can easily recommend this drive for DVD+R DL burning.
