Is there a guide for checking results of Nero CD-DVD Speed?

[JohnnyAmadeus]

I'm looking for a guide that actually explains what all the result figures are from Nero CD-DVD Drive Speed. I've had a look at the stuff that comes with Nero and that's chocolate teapot territory.

On the program itself, it would help if the axes of the chart and the lines of the graph had labels! Just what do the yellow and the green lines mean? And where should they be on the graph?

I've been checking old CD-R's and newer DVD-R's and been getting very diverging results and want to interpret them.

It seems that the program gives you all the answers but without knowing what questions are being asked and what the results figures should be, it's hard to know if my results are good or not (e.g. CPU useage @ 1 speed = 1% ; just what does it mean and what would be a good result?)

So, can anybody recommend a good explanatory guide?

Cheers,

J

Check out cdfreaks.com. They check for these errors frequently.

I wouldn't worry about the main window in Nero CD-DVD Speed,use ScanDisc and Disc Quality Test to check for bad sectors and errors.CD's use C1/C2 and DVD's use PIE/PIF,the lower the numbers the better.
Here's a guide: www.cdspeed2000.com/files/CDSpeed_eng.chm

For cd's, under ideal circumstances, there should be 0 (zero) C2 errors, though this is seldom the case. Especially with higher burn speeds and cheaper media. There should be NO CU (uncorrectable) errors. I do not recall the recommended limit of C1 errors.

For DVD's PIE (Parity Inner Errors) the maximimum (not total) should not exceed 280. EDIT: I had previously written 480, thank you to Italic for pointing out my error.

 The following could be considered the popular opinion over at the cdfreaks.com forum:

Under 100 is very good, under 20 is excellent.

PIF (Parity Inner Failure) maximum (not total) should not exceed 4.

A single spike or line exceeding these limits *should* not present a problem.

There should be 0 (zero) POF. In the case of POF, data may be lost or unreadable.

The above are the guidlines stated in the DVD specification (or so I have read).

Some things to consider:
Different drives, even of the same make, model, brand, and firmware, can give different results with the same disc. This is because consumer drives are not calibrated (matched in the way they report errors, kind of like most monitors have to be adjusted to get the color right). Thus comparing different drives should be taken with a heavy grain of salt.

There is a lot more information over at www.cdfreaks.com (as stated by another poster), at www.cdrinfo.com and their respective forums.

Cheers to all of you for your suggestions and links. If any of you bods feel like writing a guide for this site along the lines of "How to verify your burned media and interpret results" I'm sure you'd get a lot of readers.

Thanks again.

For DVD's PIE (Parity Inner Errors) the maximimum (not total) should not exceed 480.

For my opinion the limit value is 280 even if with PI of 480 disks are playable with good standalone players.
This is a good guide :

280.... err, your absolutely right. 480! What was I thinking? Thats what happens when you try to be smart while on pain killers (I had surgery, according to the doc, I had one of the largest deviated septums he had ever seen).
