Oopsie, this was not so good. We tried two discs from different packs and got the same result with both. Discs from the same packs works fine in other drives we have tested.

According to Pioneer this media should work at 16x, and we
actually got one disc to work at 16x (the one shown under writing strategy
earlier in this review) but the 8 other discs we have wrote of this type has
been 12x max.

Disappointing to see that media from a well known
manufacturer like prodisc do not even work at certified speed. But else the
result is excellent.

Again pretty good considering the low quality of this
media.
Overall thoughts: Let's start with the good thing: The writing quality is
excellent on almost every disc we threw in it. Impressive!! But to be honest we
are very
disappointed by the media compatibility of this drive. 8x media that has been on
the market for about a year is still not supported at certified speed and 16x
media that has been available for a long time before the drive was
released still do not work at 16x. And what is the point in selling a drive as
16x when it will not write at 16x to media that pioneer claims should work at
16x? And last - it uses Z-CLV writing strategy that makes it slower at 16x than
all other drives, even 12x speed with other drives is faster than this drive at
16x...
Re-Writing
data:
The Pioneer
DVR-A08XLA supports rewriting DVD-RW and DVD+RW at 4x
speed, let us write two discs in Nero and see how fast it is.
Here is the writing time for writing 4.4Gb of data to a 4X Verbatim DVD-RW disc:

The drive used 14 minutes and 59 second to write the disc
at 4x speed.
And here is the writing time for writing 4.4Gb of data to a Ricoh 4X DVD+RW disc:

The Pioneer
DVR-A08XLA used 14 minutes and 28 seconds to write the disc.
Writing Quality with DVD
Re-Writable discs:
Due to request from our readers we will add a few write
quality tests with Re-Writable media. Settings and testing procedures is the
same as used earlier in this review so you may want to go back and read them if
unsure. All discs used for these tests have been written to before, but none
have been written to more than 25 times.
