Recently in the tests of H10A@H10N and H10A@H12N I had found strange situations with very good to perfect TRTs and very bad quality scans os the burned media.Quote:Originally Posted by zeviaWell, you're not alone pchilson.

Out of specs Liteon 6S PI/PIF scan but a smooth LG H12N 16x TRT.
My drives capable of quality scans are TS-H552U, SH-W162C and 160P6S. All Mediatek based. All these drives show scans very similar.
Another oddity is that H10N or H12N "bad scans" in 160P6S suffer from a less than perfect TRT in 4163B.

Google brings you the answer in form of a DVDInfoPro Drive Suport List. Some NuTech drives are supported.Quote:Originally Posted by franz99Does anybody know if

Just for comparison I scan the same media from this post http://club.cdfreaks.com/showpost.ph...&postcount=230 with samsung SH-w162C in 8x and the bad region in 2x and 4x.
Perhaps variable results but none is good.
The original scan was done with 160P6S. - Posted:

@ pchilson
The trends of the jitter scans given by the Plextor drive and by the Lite-On are quite similar. However the max jitter value in the Lite-On scan is about two times that in the Plextor scan, yet the reverse is observed for the PIE/PIF max. How come? A plausible explanation is as follows:
DVDScan appears to report data-to-data (DD) jitter rather than data-to-clock (DC) jitter, which is adopted by DVD specifications; the former jitter may be two times as high as the latter in extreme cases. - Posted:

Interesting results, I see that all the Mediatek chipset drives indicate similar results (though actual numbers differ to a large percentage), which give a slightly different view than the Sanyo chipset based Plextor drive. The 2 BenQs however are in complete disagreement with each other, which in this particular case shows the 1650 to be closer to the other drives from a qualitative view (if you compensate for the high Jitter magnification effect).
Though, if you are looking to some correlation to ECMA compliance, they are probably nearly all wrong I suspect
(maybe the BenQ 1640 would be proven to be closer.) - Posted:

Your guess may well be right. But even though the error rates given by BenQ 1640 may be closer to those of CATS device, the differences between them may still be very large, for example:Quote:Originally Posted by TL0Interesting results, I see that all the Mediatek chipset drives indicate similar results (though actual numbers differ to a large percentage), which give a slightly different view than the Sanyo chipset based Plextor drive.

Sorry, I mean that it's not a good thing that LiteOn and BenQ give good PI/PIF values of discs that have high PI/PIF values with CATS. I would always prefer with them worse PI/PIF values than CATS.Quote:Originally Posted by TL0mognegna:

The recent CDRInfo reviews using the DaTARIUS analyzer show that (almost?) all DVD fail the tests in some ways, and I can't remember a single disc in a single drive reviewed that didn't have out-of-specs PIE, PIF or POF when burned at 16x or 18x - only some of the DVDs burned at 8x in the Plextor Blu-ray burner stay within those ECMA specs for PIE, PIF and POF.Quote:Originally Posted by TL0It may be of interest to you to read the review of Optiarc AD-7170A & preview of Lite-ON LH-18A1P on cdrinfo.com and compare the kind of results a professional analyzer gives compared to what is posted by users using consumer drives on this forum, it's interesting.
http://www.cdrinfo.com/Sections/Revi...rticleId=18307
http://www.cdrinfo.com/Sections/Reviews/Specific.aspx?ArticleId=18774
So the DaTARIUS is much pickier than most consumer drives. Does that mean that the DaTARIUS is right and the consumer drives are wrong, or does it mean that the DaTARIUS is wrong and (some of) the consumer drives are right?
No it doesn't mean either of those things. It only means that you get different results when scanning in drives with different reading behaviour. Current consumer drives are better readers than the original 1x generation of drives, so even if a DaTARIUS scan or CATS scan says that a disc is unreadable or nearly so because of Parity Outer Failures, the disc might be easily readable in current consumer drives. If OTOH a disc passes a DaTARIUS or CATS test then it should in theory be readable in any non-defective drive.
EDIT:
Just to clarify, this does NOT mean that I think that all consumer drives are as reliable or useful for scanning CD/DVD media as DaTARIUS and CATS scanners.
But it means that I think that no drive, whether it's a consumer drive or professional scanning equipment, has any monopoly on the "truth" about the quality of a CD/DVD. Such a "truth" does not exist in my opinion, since the quality is not an objective measurement but rather the result of interaction between drive and media.
It also means that I think CD/DVD media could still be readable on many consumer drives even if the media fails a DaTARIUS or CATS scan.
And finally it means that in my experience, it's possible for a CD/DVD to produce disc quality scans on consumer drives that are within ECMA specs, and the same disc can still be unreadable in some other drives.
Thanks to muchin for pointing out the possibility that my statements above could be misunderstood.

Hi Drage
Quote:Originally Posted by DrageMesterthe DaTARIUS is much pickier than most consumer drives..
Current consumer drives are better readers than the original 1x generation of drives
- probably the reason why I have to resort to tests putting more stress on the reading process (= scanning @12X or 16X) to achieve some sort of predictability for my standalone DVD players.. but not for my PC drives, which will all easily "eat" a disc passing a 4X, 5X (Nec) or 8X scan in any of my drives.
Yet, I'm more or less convinced that our burnt discs aren't nearly as good as we come to think by scanning them in Liteys @4X. ECMA standards were published at a time when our drives weren't so good readers (as you just -implicitely- pointed), and professional scanning devices could well still be, nowadays, calibrated to reflect this 'old' behaviour.... so are ECMA standards numbers to be applied 'as is' in home scanning? I highly doubt it. Though I don't see how we could introduce a different standard for error levels...
So one approach (the one you explain) is to consider that as drives are now much better readers, such bad results as shown by Datarius don't mean much in real-world, and Litey (or Benq) scans @-forum-standard-speeds (4X, 8X) can be trusted for most uses.
Another approach is to consider that our scanning drives are too good readers to properly reflect a burnt disc's potential reading quality in a wide range of drives, particularly in older (or cheap) standalone players. With this approach, one will not rely on a single testing drive but use at least two 'scanners', and/or put more stress on the reading process by scanning at higher speeds.
Both approaches are legitimate, and in fact reflect different necessities.
Personally, I use both.
For data/backup discs, a good-looking scan in a Benq or LiteOn or Nec (3540A ONLY
- all other models highly suspect) @-forum-standard-speeds + a passed (= prefect) TRT in at least one drive and I'm good.*
For video discs, on the other hand, I scan in at least two drives, and at higher speeds. Only this way can I be (99%) sure that the discs will play flawlessly in most standalone players, including older ones.
*(Since scanning takes time, even for the data/PC discs I first use higher scaning speeds. Then if the error levels skyrocket at the end of the disc, I re-scan this area @ lower speed.)
