unfair -> dvdinfopro and asus some results (7/3/2005 7:53:31 AM)

dear friends
could you explain the results,pls
in program's local help file it has been written pi should be under 280 and po should be under 32
if this is true ,the media is already death :)
what should PI Avg and PO Avg be ?
media is dvd-r 1-4x princo white

>>in program's local help file it has been written pi should be under 280 and (po should be under 32 )
This is not correct po should be 280 or less , only pioneer clones and pioneer scan po all else scan pif and pif is the
one that should be 32 or less.

As that is a scan of pie vs poe you should read it like this

pie should be 280 or less
poe should be 280 or less
lower is better most good burns will
have level under 50 pie and poe will be low also.

As these graph are way over that this would mean they are poor or even bad burns
But scanning is relative and you should also try a test play if its video to see if your
settop will play them ok, if its data you should try to see if you can read the files back to HDD.

With the Pioneer 109 the results are varied between different drives so you can only compare you results with other media tested in your drive and relate the results to each other.
I have had similar results to you on media that has been good but you cannot compare your results with any other Pioneer drive because they will be entirely different.
Just use your drive to get comparisons with your media.




unfair -> RE: dvdinfopro and asus some results (7/5/2005 3:41:05 PM)

what about single peaks?





zebra -> RE: dvdinfopro and asus some results (7/5/2005 4:53:23 PM)

Again, very difficult to tell. :(

The best suggestion in this situation (as Pioneer drives have such an odd way of reporting parity information) is to ALSO run the RPM test and the Error block test, and post us the resulting pictures here. We will then be able to get a better idea of how the media has performed. Those large peaks/spikes do not tell us much *yet* but they may in conjunction with the two other tests you run. ;)

Look forward to seeing the results!

i want to share other media results which is better
and could you explain the results detailed,so i wouldnt ask you again :)

zebra -> RE: dvdinfopro and asus some results (7/7/2005 3:45:44 AM)

Ok.

The first graph (PI/PO test) cannot tell you much here, as Pioneer type drives report information in an odd way. In general, Parity inner should not exceed 280, Parity outter should not exceed 32. This would suggest there are some problems with the media quality.

The next graph is more important! Notice that your yellow line graph is very wavy and irregular. This indicates that the drive is finding it difficult to read the disc back! Media quality is questionable! Might not be too good at all!

Finally, you have green CRC error check. This is good, as it means even though the media quality might not be perfect, it still has no damaged sectors, so your data is safe. :)

Try some different media...and redo tests, and we can compare them again, to see which is best. :)

but my friend said asus doesnt support pif so your both pi/po values must be under 280-280 not 280-32




emperor -> RE: dvdinfopro and asus some results (7/7/2005 3:49:35 PM)

unfortunaly, PI/PIF scans with Pioneer drives are not a good way to say if a media has good or bad quality, i would just use the transfer rate graph, if its smooth, probably you won't have much problems

Everyone here ( apart from Flash ) is leading you on a wild goose chase[:D].  Parity Outer PO should NOT be under 32. (* slaps Zebra [:D] *)  They are confusing PO with PIF.  Pioneer drives dont report in an odd way at all  they just report PI and PO rather than PI and PIF that most other drives do. Infact another scanning utility shows it as PIF too which just adds to users confusion.  For Pioneer drives both the PI and PO should be under 280.  However never just use a pi.po scan by itself,  use it as part of a test.  Always check with CRC check as that is the most important one of all,  and also test in players.   Especially dont compare pi.po scans done by others in different drives.   Use it to compare burns done in your drive on different media and speeds.

cheers

dear Friends,dont you think it has been a tutorial for people who start to use dvdinfopro?i think we should improve this topicso i am going to send all my results... and nicw i understand what you say :) thanks again

O.k., I have a question here.. what *IS* the difference between PIF and PO ? It isn't explained in the wiki or anywhere else that I looked. Here is what I think I know so far:

PI = PIE (synonymous) = Parity Inner Error, will undergo PI correction attempt next
PIF = Parity Inner Failure, occurs if inner parity correction attempt failed

now...

PO = POE (synonymous) = Parity Outer Error, e.g. errors that were not corrected with inner parity? Wouldn't that mean PO = PIF? If not, then in general, is PO > PIF, or PO < PIF ? And why?!

And of course

POF = Parity Outer Failure, presumably happens when a PO (and a PIF?) could not be corrected by outer parity. This is a "hard" error that presumably should also give a CRC32 error when scanning a CD, and it cannot be further corrected. With a bit of luck, a disk that gives a POF can probably still be read without a POF on a different (better) drive.

Please clairfy... Thanks!!
