Thanks
That's a pretty good scan.
Here is an example of a bad scan:

喂
我在這個光碟測試新。 候補的我向上掌握和指揮員昨天與一BenQ 822A與固件B3IC一起一起。 我使用一個4x Ritek R02 +R 光碟。 它在8x燃燒。 我認為掃描是好的，但是我不能確信。 任何建議將被感激。
感謝
那是一次很不錯的掃描。
這是一次壞掃描的例子︰

Notice the PO Failures (they should be 0), high jitter (should stay below 12%) and high number of PI Errors.
This was a 4x DVD+R which was burned at 8x. The scan clearly shows that it should have been burned at 4x.
The first part of the disc which was burned at 6x is good though.

注意到郵電亭失敗(他們應該0歲)，高的緊張(應該停留低于12%)和高的PI 錯誤的數量。
這是被在8x燒毀的4x DVD+R。 掃描清楚顯示它本應被在4x燒毀。
可是，被在6x燒毀的光碟的第一部分是好的。

PI/PO checking with Ricoh drives is limited but according to my tests they're pretty accurate.
I've noticed a few times that scans from LiteOn DVD burners don't agree very well with other drives.
Here is an example:

我在4x 用LG GSA-4082B A208固件燒毀一個YUDEN000T02 光碟。
有1.05個固件的理光MP5240A 報告超過160個PI 錯誤最大， 當時輕便在上加固件832 VS0B S的SOHW-812 S 報告適合那些同域的那些光碟的最大的錯誤13 PI。 關於1.3GB，和我使7，200個PI 錯誤和2.7x 一般。 理光開始7x 和輕便在上確定給4x。 麥克斯2個PIF 錯誤。
與理光核對的PI / 郵電亭駕駛有限但是根據他們相當準確的我的考試。
我已經注意到從LiteOn DVD 燃燒器掃描的幾次不非常好同意其他運動。
這是一個例子︰
Ricoh chipset
http://cdspeed2000.com/forum/AOPEN_...-2004_05_41.png
ALI chipset
http://cdspeed2000.com/forum/AOPEN_...-2004_05_04.png
Mediatek chipset
http://cdspeed2000.com/forum/LITE-O...-2004_13_56.png
The same disc was scanned with four drives (including the BenQ mentioned in my previous message) who are using a different chipset (Ricoh, ALI, Philips and Mediatek).
They all agree more or less (problems starting at the position where the burn speed switched to 8x) except the LiteOn.
__________________
相同的光碟被掃描， 由於4 運動(包括BenQ被用我的以前的消息提及)正使用一個不同的晶片組(理光，阿裡，菲利浦和Mediatek)。
除LiteOn之外，他們或多或少全部同意(問題在燒傷速度轉向8x的位置開始)。

Also can the PIF graph in auto range mode start with a scale of 4. As this is the accepted maximum PIF for ECC 8/1 it might as well show full resolution for burns with PIFs under this level.
And can the disc quality test options be retains between launches of the test dialog or program execution.
Thanks for the great tool.
C0deKing
Thanks for the suggestions.
I've made a workaround for the speed issue with the 832S drive. Speed settings for this drive are now hardcoded and not detected anymore.

這包括832 S速度問題嗎？ 我知道固件有一個問題，但是KProbe沒被它影響。
此外用汽車範圍模式的PIF 圖能從一個4的規模開始。 因為這對于ECC 8/1是被接受的最大的PIF，它最好在這水準下用PIFs顯示燒傷的詳盡的決定。
並且能那些選擇質量檢驗光碟在汽艇的對話或者實行計畫那些考試的之間保留。
感謝大的工具。
C0deKing
感謝建議。
我已經做速度問題用832 S 運動的一種變通辦法。 這運動的速度底座現下是hardcoded並且不再發現。

That's true
Although the 3 other drives (especially the BenQ) show that you may get good results if the disc is burned at a lower speed.

實際上，他們全部同意它是一個crappy 光碟。 我懷疑也有一些掃描速度的差別。
那是真的
雖然3 其他運動(特別BenQ)顯示如果這個光碟被以更低的速度燒毀，你可以得到好結果。
