I’m suprised that even you didn’t entirely get my point, [B]scoobiedoobie[/B].
One of the driving ideas behind these guy’s project is to testify of media quality, and have a rating system for it.
As we should all know by now, 4X scans in Liteys or Benqs (Plextor 2X scans being an expection - a for [B]Drage[/B]) don’t attest of media quality.
> Comparisons with CATS have shown that many discs can look good in homemade scans @4X or @8X, yet appear out-of-specs in professional testing equipment.
> There has been many examples recenty on this board that discs showing good PIE/PIF scans at “standard” speeds can nevertheless have a troubled reading curve in a TRT.
BTW you mention that these cases are scarse, but that’s probably because you don’t deal with lower quality media. That’s what I’ve learned: [B]lower quality media’s first flaw is, in general, poor mechanical properties, leading to reading issues at high speed near the end of the disc, where the disc’s tilt and stability is the most important.[/B] This true nature doesn’t necessarily show in “standard” scans, actually it’s rare that it does.
So if they really build this database with only PIE/PIF scans @4X, [B]we’ll have another misleading source on the net making people wrongly think that they get the best media if they choose the best looking PIE/PIF figures in 4X scans, which is as sound as choosing the “best” car by choosing the fastest engine.[/B]
“Good” media is about good [I]real-world performance[/I], not good-looking homemade scans (with maybe some exceptions with very controlled methods including scanning at different speeds in different drives, if that). The only trustable real-world performance test existing for us, poor end-users, is the transfer rate test. Dismissing it when building such a project is IMO foolish, and will confuse even further thousands of users on the net.
[B]Then people in the know about testing will feel very, very lonely and helpless when facing the misconceptions of these thousands zealots of the “quality scan” dogma.
I don’t want that to happen, personally. Things are already bad enough.
Do you know that the very people who originally created the “media tests section” here at CDfreaks, who happen to be among those who introduced PIE/PIF homemade scanning to the general public, have had second thoughts about it, and wondered if it was not a mistake considering all the consecutive misconceptions and unsound uses?
I won’t rest my case easily on this one. The last thing we need is another source of what I consider as [B]misinformation[/B].
