Okay...兩點回應....補充您所忽略沒提的∼

1.
我想對照組是非advanced test，所以相對地4.7.0.0版與之前版本所測的jitter是對的。

原文「Jitter: unfortunately an incorrect formula was used to calculate jitter so please ignore this value for now (the jitter from the standard Disc Quality test is correct).」


2.
不只是Benq，大部分機器都只有BLER (C1) and E32 (C2) errors
(原文：「Most drives report BLER (C1) and E32 (C2) errors.」)，此外Plextor是分別回報C1 = E11 + E21 + E31，C2 = E22，CU = E32，所以Plextor也沒把C2將E22+E32都納入，所以不知道錯誤之說從何而來？
而且DrageMester大大也說了，像Plextor這樣分是uncommon的。如果說C2應該將兩個都納入，那Plextor也是處在錯誤的分類裡面。不過話說回來，當然提供多一點資訊越好，所以才有Advanced test被加入。

而Lite-on DVD ReWriter又是不一樣的情況，它的C1報的不是BLER。

原文：
C2 error reporting
Most drives report BLER (C1) and E32 (C2) errors. It's true that it would be more interesting to show E22 errors as well but not many drives can report this. If E22 would be combined with E32 then it would be difficult to know if a disc is really bad.
這裡清楚解釋了為什麼在大多數機子中，C2不是以E22+E32被回報。


最後，這是ErikDeppe對Benq機子當作CD scanner持肯定的看法：
