Write Quality Tests MKM 001
Dual layer media follows the same rules as single layer, but there are certain points on the disc where errors are known to occur the most. We have noticed that the part of the disc where the transition from layer to layer happens is where the PO errors have shown up. Our results are as follows:
We didn't have much luck getting dual layer media both to burn on all drives, since the Sony DRU-710A and MSI DR16-B had trouble writing a successful dual layer disc, and if there was success, to be recognized on the Plextor drive. The DVR-108D and DW1620 came out clean with 0 PO errors each with NEC following with 3 PO errors. The SOHW-1633S was another drive we had luck with, but a successful write was the end of it. PO errors on the dual layer media from that drive hit 192 and were all located between the 2GB and 4GB mark where there were also a few million PI errors!
The DVR-108D performed exceptionally well producing on 546 PI errors on the MKM 001 media. NEC followed with 261224 PI errors which held it and the Pioneer unit at the top two spots.
The Q-Tools screenshot of LiteOn's burn shows the majority PI errors between the 2GB and 4GB range.
It's too bad that there were only 4 drives on which we could test write qualities. Hopefully, future firmware releases will fix compatibility issues on the drives that we have tested in order for media to be recognized correctly on a wider range of hardware.

#15 DL is important to me because I know the price of media will drop and I want the drive I buy to be as useful as possible for the longest time possible. I might be buying it today but I will be using it tomorrow :) Overall you make some good points :)I think this is a difficult time to do this kind of article, because other improved versions will be available before the end of the year. For example, the Plextor 716A will be released with SATA capabilities.
I think its wierd that you couldn't get the Plextor drive in time, as I know this product has been reviewed by others.

A recent (17 August) article in PC World advised extreme caution when buying an OEM (versus retail) DVD burner. It said that OEM units "carry no manufacturer's warranty, lack burning software and are ineligible for firmware upgrades" (therefore costing more in the long run). Many examples were given. I would appreciate advise as to whether this is percieved to be a real concern. If so, NEC has no retail outlet - how would you buy a non-OEM unit?southernpac - Monday, November 1, 2004 - link

How about overburn tests? I have many times wanted to burn 50-100MB more than a standard single-layer disk but failed because my drive or software won't do it.Codyman - Monday, November 1, 2004 - link
I'm kinda wondering if a PX716A couldn't get crammed into this test somehow. Been waiting for this review in hopes that it would've been in this test and I haven't been waiting the extra couple months for nothing.danidentity - Monday, November 1, 2004 - link
I'd like to see a list of recommended media for different speed grades (4x, 8x, etc.) for different burners.techfuzz - Monday, November 1, 2004 - link
Why weren't the firmware on all the drives tested brought up to at the very least the most recent officially released version? For example, NEC's current official firmware is v2.17 where the v2.16 used in this roundup is the original firmware as-shipped from the factory?!Bozo Galora - Monday, November 1, 2004 - link

Doesn’t Samsung make a Dual Layer DVD burner? If so why isn’t it in this roundup?MIDIman - Monday, November 1, 2004 - link
Yay! I'm a winner! I was waiting for this article, but couldn't wait long enough, and picked up the NEC two weeks ago. Couldn't be happier.Here's hoping for better Ritek 8x/16x support...
