Pioneer DVR-111 DVD Burner Review

 




 


The specifications of
this drive tell us that it should write DVD±R at 16x and DVD+RW/-RW at 8x/6x. In
this part, we will measure the write time for various types of DVD+R/RW and
DVD-R/RW discs. We will also focus on write quality and media compatibility.


DVD-Writing
performance:






In this test we will
measure the time for writing to DVD±R discs. We used Nero Burning Rom to burn an
ISO compilation containing 4480MB of data. We used the Disc-At-Once write
method.

The results are about
average when compared to other drives.


Write
quality:






You should
first notice that this is not a scientific and professional way to test the
discs. But according to our testing done in recent months, we would conclude
that there is a clear link between the quality reported when scanning the disc
and the playability of the disc in different devices. Also notice that different
drives report different amounts of errors. K-Probe was designed to work with
Lite-On
DVD-Writers,
so we recommend
using a DVD-Writer from
Lite-On. In this test we
use a
Lite-On SHW-16H5S
DVD-Writer, as already said; remember that scans done with a
Lite-On DVD-ROM or
Lite-On combo drive
can’t be compared with the results obtained with a
Lite-On DVD-Writer.
Also remember that
different PI/PO
ECC sum settings along
with different reading speeds in K-Probe will affect the result, we use these
settings;  PI
(Parity Inner) set to summarize 8
ECC blocks,
PIF (Parity
Inner
Failures) set to
summarize 1
ECC block, reading
speed: 4X
CLV (Constant
Linear Velocity). Setting the PI sum to 8 and the
PIF sum to 1 will give
a result that we may compare to the standards for
DVD+R/RW and
DVD-R/
RW.


But what is
a good scan? That is a discussion that we don’t think will end soon, as
different drives report different amount of errors, some players are more
picky about media than others, and so on. But as a comparison we present you
with a scan from two pressed DVD discs:



This scan shows the results from a pressed DVD-Video disc
(
GoldenEye).


 


This scan
shows the result from a pressed DVD-Video disk (The Green Mile). Notice the
error jump when shifting to the second layer (the error level actually drops
from the end of the first layer to the beginning of the second
layer).


If you read
below, you will see that both the pressed DVD-discs are well within the
standards.


Download
the
ECMA 267 Standard for
DVD-ROM, the
ECMA 337 Standard for
DVD+R/RW and the
ECMA 338 Standard for
DVD-R/
RW at http://www.ecma-international.org if you want to look
at the standards for yourself. Here is some data from the
ECMA standards (same for
DVD-ROM, DVD-R/
RW and DVD+R/RW):


Random
errors:


A row of an ECC Block that has at least 1 byte in error constitutes a PI
error. In any 8
consecutive ECC Blocks the total
number of PI errors before correction shall not exceed 280.


Here we see
that a PI error is defined as a row in an
ECC block having 1 byte
or more containing errors and that the sum of PI errors in 8
ECC blocks after each
other should not exceed 280 PI errors.


But what is
a row and what is an
ECC block? Again we
refer to the
ECMA standards. We do
not copy and paste everything, but if you’re interested, look in the
ECMA standards. A row is
182 bytes long where the last 10 bytes contain PI (Parity Inner)
information. An
ECC block is 208 rows
long where the last 16 rows contain the PO (Parity Outer)
information. This gives us a maximum possible PI error amount of 208 errors per
block and for 8 blocks after each other this sum is of course 8 times higher,
giving a maximum possible amount of 1664 PI-8 errors. In practical use, a disc
with 1664 PI-8 errors is unreadable.


According
to our tests the specified max PI-8 sum of 280 for good discs seems to be a good
guideline, as some readers have problems reading discs when the PI-8 errors is
over 300 and most players starts to have problems when the PI-8 error level
reaches 600 or more.


But what
are the
PIF errors that K-Probe
reports? They are Parity Inner Failures, meaning errors left after PI
correction. Only the
ECMA 337 standard
describes the Parity Inner Failures. So how is a Parity Inner Failure defined?
Here is what the
ECMA 337
states:


‘If a row of an ECC Block as defined in 13.3 contains more than 5 erroneous
bytes, the row is said to be ‘PI-uncorrectable“.”


In theory, an ECC block may in the worst case have 208 PIF since every ECC block is 208
rows long. But the ECMA 337 standard goes further and
specifies the max amount of accepted PI Failures (uncorrectable errors) allowed on a good disc:


‘In any
ECC Block the number of
PI –
uncorrectable rows should not
exceed 4.” 
 


This means
that when the
PIF sum is set to 1,
the maximum error value should not exceed 4. The theoretical maximum value for
PIF is 208
errors.


But what
makes a disc unreadable? A
POF (Parity
Outer Failure) error will make the disc unreadable, but K-Probe
does not display the
POF’s.


Notice
that there are other aspects such as disc reflectivity, jitter, tracking errors
and so on that also will affect the readability of a DVD disc ‘“ but for this we
do not have measuring equipment available.


Also,
another note is that we have scanned the discs at 4X
CLV speed, by lowering
the speed to 2X(DVD-R/
RW)/2.4X(DVD+R/RW) or 1X the amount
of reported errors may drop on some discs. We scanned at 4X
CLV due to lower speeds
taking too much time.


To see if
there is a connection between the reported amount of errors and readability of
the discs we also include the reading curve from a NEC ND-3540A DVD-Writer. The
reason why we have changed the reader is that some companies disliked that we
used a modified firmware to obtain 16x reading speed. So to please them, we are
now using a drive that reads
DVD+R/-R media at 16x as default. A small speed reduction near the end is still
accepted on good discs, but serious reading problems or reading failures is a
bad sign.


Easier explanation on how to
read the test results.






Maybe this
has got too technical, and you are wondering what to look for in
KProbe reports?


Use this as
a guideline for good discs:



  • PI (Parity
    Inner):
    No larger areas
    on the disc should exceed 280 PI-8 errors, do not worry too much about high
    single spikes that exceed 280.

  • PIF (Parity Inner
    Failures):
    No larger areas
    on the disc should exceed 4 PIF-1 errors, do not worry too much about high
    single spikes that exceed 4.

And as
always; lower is better


And look at
the reading curve; if it looks clean with no dips it should be good, a small
slowdown near the end is accepted.


DVD+R media compatibility and write quality:






In these tests we will be
using a Lite-On SHM-165P6S with firmware MS0M along with K-Probe to measure the
disc quality. We will also be using the NEC ND-4570A with firmware 1.02 along
with CD-Speed for our read-back tests.

So far the
Pioneer DVR-111 writes DVD+R with excellent quality. DVD+RW write quality is ok
but could be improved.
