DW800A DVD+RW -
more 8x DVD recorder has entered the dvd recording
market. BenQ, after the DRW400A 4x DVD recorder, reveals the new DW800A. The
technology behind the drive is build under the joint venture of BenQ and Philips,
based on Nexperia DVD+RW reference design.
8x DVD recording market
has already reached a mature stage, the BenQ DW800A is going to confront some
Smart writing control
To ensure optimal writing quality over the entire disc at higher writing
speeds, BenQ uses the
Walking OPC algorithm. For the first time it is possible to directly measure
and optimise the actual writing
quality during the writing process. As DVD writing consists of packet writing,
seamless linking is not required
in order to perform a WOPC.
At certain intervals, the writing process will be briefly interrupted, the
writing quality directly evaluated and the
writing power adjusted accordingly, if required.
addition, the "Tilt Control" always keeps the writing angle
at 90 degrees on the
disc surface to ensure uniform writing.
Near the end of the disc, the risk of warping is higher so the frequency
of the tilt calibration will increase
accordingly. The writing process will be briefly interrupted,
the tilt measured and the OPU repositioned if required.
The best reading and writing quality can be obtained if the angle between
the disc and the laser beam is 90
degrees. However, if the disc is warped, the laser beam will no longer be correctly
positioned which will cause a distortion of the laser spot which will result
in decreasing writing
quality if it is not corrected.
Tilt Servo Control maintains the best writing angle, while the Walking
OPC provides optimized writing power. Thus ensuring the best writing quality
the whole burning process.
DW800A also uses the Seamless Link technology. The technology
automatically monitors the recording status to prevent buffer under run from
BenQ's Seamless Link allows the drive to store
the RecEnd address, the point in the data to which the recording mechanism
has progressed, and pause the recording before a buffer under run occurs. When
the buffer is again full, a Seamless Link-enabled drive locates the RecEnd
address and resumes the recording process. The gap between the stop and restart
point is closed, while managing the recording process precisely and transparently-eliminating
under run errors while maintaining recording accuracy.
Book Type Management
BenQ DRW800A allows the user to easily change the format to be more compatible
with DVD readers. BenQ's Book Type Management enables you to manage the format
between DVD R/+RW to DVDROM, the accepted standard format for DVD Players.
The BookType can be either changed through Nero Burning Rom or via the BookType
software bundled in the retail package. More information is available
further on on this page.
As can be seen in the manufacturers specifications listed below, the drive
supports 8x DVD+R, 4x DVD+RW, 24x CD-R and 10x HS-RW
12x for DVD-ROM.

According to Nero Info Tool the drive has an 8MB buffer size.
All media formats are supported by BenQ DW800A except DVD-RAM. RAW DAO 96 writing
(CD) is also supported. The drive unfortunately is not compatible with Mount
BenQ DW800A, as with most DVD drives, uses the RPC II region control
allowing the user to change the drive's region 4 times. For our tests,
code to 2 (Europe).
- The drive
In the front panel there are from left to right, the DVD
rewritable logo, BenQ logo, and the CD rewritable logo, all on the
loading tray. The supporting
speeds are given below the manufacturers logo at centre. Below the tray are
the headphone jack, volume control, and power indicator
led located on the left. The led is green while reading
and orange when burning. On the right you are the next track/skip and
buttons. For emergency there is the usual eject hole, this time located in
On the rear panel you can see the digital and analogue audio outputs
(SPDIF), the IDE connector
and the power input.
Removing the screws and opening the drive's cover voids the drive's warranty.

Below is shown the main chipset used in the drive, which is
the Nexperia PNX7850 from Philips, which is the same as that used in
DVD recorder, the DVDR824P and also CyberDrive's DX082D drive.
- Retail package
retail package includes the DW800A recorder, an installation guide, the warranty,
screws, a guide for InterVideo WinCinema software, an audio cable and two blank
media (one DVD+R and one DVD+RW).
As for software, there are the Sonic RecordNow v6.5.1, Sonic DLA v4.52, WinDVD
Creator Plus v2.0, for editing, and WinDVD Player v4.0. The book type change
software is also included.
BenQ DW800A was connected to our test PC and it was identified
as "DVD+RW 8X4X12" under
WinXP OS. All tests were done with firmware revision vB2H7.
By the time we write these lines, BenQ has launched firmware upgrade vB2I7.
On the following pages you can see all our test results and in addition a
comparison with two other DVD burners, the Optorite DD0401
LiteOn LDW-811S DVD±RW drives.
