detail information

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

The Memorex 16X-DDL-IN 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 8x for DVD+R DL, and 6x for DVD-R DL.

For manufacturer and media information, we will use Nero CD-DVD Speed version 4.11.

Testing procedure:
We created an ISO Image from a pre-authored DVD-Video compliant file set, with a total on-disc size of 8109 MB. We used Nero CD-DVD Speed to create an ISO test disc, this way we could also see the writing strategy the drive uses. Below are the results:

Nero reported a successful 8x burn with the Maxell 2.4x media in 18 minutes and 42 seconds.

PI errors are good on the 1st layer, PI and PIF errors on the 2^nd layer are higher but within specification. The result is very good.

Nero reported a successful burn with the Ritek D01 2.4x media in 44 minutes 19 seconds @ 2.4 write speed.

There is clearly a PIF increase at the layer break of the disc. The PIF errors are out if specification yet the transfer test shows no problems. The result is ok but could be improved

As we can see from our results, both drives were able to read all our test discs with very few problems. There are the usual slowdowns at the layer breaks. This should not cause too much concern.

Let's compare the Memorex 16X-DDL-IN with some other DL capable drives.

DVD-R DL

As mentioned at the top of this page, the Memorex 16X-DDL-IN supports the DVD-R DL standard at 6x. 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 4.11:

Again, we used Nero CD-DVD Speed to write an ISO Image.

The Memorex 16X-DDL-IN took 20 minutes and 48 seconds to write the Verbatim DVD-R DL media at 6x.

The result is very good.

Standalone DVD-Player compatibility:

We only have 3 standalone DVD-Players available to test the DVD+R DL medias (Book Type: DVD-ROM) and the DVD-R DL media (Book Type: DVD-R):

• Panasonic DVD-F87
• Toshiba SD-3750
• Samsung DVD-P4

Compatibility results: 

All DVD Standalone devices played the Memorex 16X-DDL-IN burned DVD+R DL media. But only one DVD Standalone device would play the Memorex 16X-DDL-IN burned DVD-R DL media without any problems.

We would like to mention, that the compatibility issue with standalone DVD Players/Recorders and the DVD-R DL media format is caused by incompatibilities with the standalone devices used in this review, and not the Memorex 16X-DDL-IN or media format used.

Summary: Although all the discs were readable in our scanning and read-back test drives. We would like to see some improvement in write quality.

To round of this review, we will run some advanced tests on the Memorex 16X-DDL-IN on the next page…
