DVD+R
Dual Layer writing speed and compatibility:
The
Pioneer DVR-A08XLA supports the DVD+R9 DL standard for writing Dual Layer discs with a size
of 8.5 GB at a writing speed of 4x.
Testing
procedure: We
created a new compilation using Nero 6 and wrote it using the Disc-at-once
writing method:

Verbatim DVD+R9 Double layer 2.4x written at 4x. Total writing time is 27 minutes and 2
seconds.

There
were no noticeable reading problems, but we dislike that error spike around the
layer change.

Again we
could see that the ritek double layer media fails, we tried two discs as the
first one was not even detected by any drives. Looks like Ritek has some quality
improving to do or that the drive manufacturers have some firmware optimizing to
do.

The
Verbatim DVD+R9 DL discs written by the Pioneer
DVR-A08XLA works fine in our
Summary:
As long
as you use Verbatim double layer media there should be no problems and the drive
automatically bitsets the discs to
DVD-ROM.
Before
we round off this review, let us run the drive through some advanced tests at
next page…
