Does anyone know how to interpret the numbers on DVDinfopro or Kprobe. I have scanned a couple of burnt discs and the program will produce numbers such as PI, PIE, Po (max, avg, peak) etc. I'm not sure what to make of the results. I am assuming the lower the numbers the better however what range is considered acceptable? I scanned a Taiyo Yuden and a Khypermedia (CMC) disc and both had about the same numbers.

I to am interested. CDFreaks.com people talk about that alot. Have you ever visited their site. Very technical oriented.


First of all what software are you using and where did you get it? I have software(DVDIdentifier) that tells me who made the media and it's speed, etc. But am interested in testing my burns as well.

I retrieved the following from another site (can't recall which one, though):


PI total = Sum of all Parity Inner Errors (both correctable and uncorrectable) on the whole disc


PI Avg. (APIE) = Average number of Parity Inner Errors per block on the whole disc


PI Peak (PIE) = Maximum number of Parity Inner errors in a single block


PO total = Number of Parity Outer Errors (both correctable and uncorrectable) on the whole disc


PO Avg. = Average number of Parity Outer Errors per block on the whole disc


PO Peak = Maximum number of Parity Inner errors in a single block


Jitter Avg = Average Data to Clock jitter as a percentage of channel bit clock period


Jitter Peak = probably just running smoothed jitter figure (would have to ask NuTech/Philips) or could be a real Peak value of tilt (unlikely)

Here's a good thread:

I briefly read thru the testing discussion at CDFreaks. I'll be re-reading it again as well as posing some questions on their forum. Bottom Line is- better media results in fewer burn errors, etc.


I wonder what they mean by discs lasting longer? As I've said before all the discussion between dash and plus disks compatibility, prices, etc are minor if the media fades and can't be read or retrieved due to dye disintegration a few months after burning.


Taken from CDFreaks. "In the end, a disc only has to meet DVD specs at 1x read speed, and this is clearly adequate for movies. But if you can acheive low error rates at higher speeds, this is more likely to produce discs that last a long time and have fewer playback problems or compatability issues".

This is more part of the folklore that accompanies new technologies. A more formal study of media (I don't have the link handy at the moment) pointed to studies indicating that burn speed made no difference to media behavior in long-term testing.

I downloaded DVDinfopro from this site:
