DVD+R/-R Double Layer writing speed and compatibility:
The Philips DVDR1660 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/4x.
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:


Verbatim media
Nero completed the burn successfully with the Verbatim media in 47 minutes and 2 seconds.
Let us take a look at the K-Probe result:

The result is very good.


Verbatim media
Nero completed the burn successfully with the Verbatim media in 31 minutes and 58 seconds. According to the total writing time there must have been a slowdown in speed since the writing time is too long for an 8x burn.
Let us take a look at the K-Probe result:

As we can see from the KProbe scan there are some high PIF's around the layerbreak. And in the reading curve we can see the slowdown near the layerbreak.
Let us compare the Philips DVDR1660 results with some other DL capable drives.

DVD-R DL:
As mentioned at the beginning of this page, the Philips DVDR1660 supports the DVD-R DL standard at 4x. Again, we used Nero Burning Rom 6 to write the DVD Image:


The Philips DVDR1660 used 32 minutes and 28 seconds to write the Verbatim DVD-R DL 4x media at 4x.

Standalone DVD-Player compatibility:
We only have 4 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/DivX Player MD7457
- Medion DVD/DivX/NeroDigital Player MD80796
- Red Star DVD-Player 230G
- Mustek R100A DVD+R/W Recorder

All DVD Standalone devices played the Philips DVDR1660 burned DVD+R DL media. But only one DVD Standalone devices would play the DVD-R DL media.
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 Philips DVDR1660 or media format used.
Summary: The results are ok. However, some room for improvements is always welcome.
Before we round off this review, let us run the drive through some advanced tests at next page…
