Interesting opinions there RJW!
However, would empiracle evidence suggest that this:
Pioneer knows to well that there drive are tuned of excellent readers for bad dvd-recordables.
...is a somewhat false statement? It is an interesting point you make, in that Pioneer would not want end users to "see" the quality of a write from their hardware - but I don't think there is a strong case for Pioneer drives having poor write quality as a generalised statement.
My statement is not false. At least in the way it was how my intentions were but maybe things got a little lost in translation from what I said or you just can't read like a lot of folks can not seem to do.
What I tried to say is the followeing
Pioneer drives are probally one of the best readers out there for bad dvd-/+r's. And for this reason they can read back stuff that's outside the standards and will be problematic on quite some other players.
Most known better compannies(Plextor/ Pioneer/Philips/ Lite On) try to optimise the read performance of a drive to be it as good as they can get it. Come On that's very well known. If you don't know then check some firmware log files. Okay I know Lite On might not list it. they probally only say match more media. But try to read some stuff back with a new firmware that was very problematic with a much older firmware. 9/10 that the performance has improved unless the media has gone even worse in time.
However the small brands and no name stuff just try to get a performance that supposed to be in the standards.
Now Pioneer has optimised there drives very good or else they couldn't get 100% scores on mannipulated test media.
I should say check arround for some test media which was mannipulated on purpose. Or try to get results of disc's with very high jitter as one of the main problematic parameters while the other stuff is allmost inside the standards and the effect that disc has on Pioneer drives as a reader and on other players. (mostly video players ). You will see that all Pioneer drives are able to read such a disc allmost perfect back. While drive that are build to handle inside the standards can not do this.
Also I know there write quality is very good.
And I never made a negative statement about the write quality. If you look arround (which is something most folks can't do then I would recommend Pioneer a lot of times because of the writeing quality being that good.)
Still a good burner + Bad Hongkong media = Problematic disc.
Which a Pioneer drive might be able to read back withouth problems why quite some stuff of the competition will have problems (dureing the burning or the reading !)
