Alex i think the problem here is the quality of the sold media, as you know there are fake media and even if you buy a pile of the same media, quality varies so...safer to go slower

There is no simple answer to the original question. Every answer should be, "It depends on..."

A burner manufactured yesterday may burn better or worse than the same make/model manufactured today. A pack of Taiyo Yuden DVD-R bought yesterday may be better or worse than a pack bought today. Yesterday's pack may burn better at 4x than at any other speed, and todays pack may burn better at 12x than any other speed. The dye layer on yesterday's disks may be either more or less stable than todays disks, so may last a longer or shorter time than todays disks. One pack may last longer if burned at higher speeds and another pack of identical disks may last a longer time if burned at lower speeds.

Who knows? It is something that only time (and well kept records) will tell.

I would like to know one thing from our experts, there are 2 different things:

1) A quality burn with low PI/PIF errors
2) The aging of a burned DVD

On which one has the low burning speed the greatest influence  and why ?

Is a low error rate measured immediatly after the burn a warranty for good aging ?

Immediately after burning can give false readings due to the temperature of the disc, it is advisable to give the discs 30mins to cool down before testing. The results obtained cannot give any indication as to the aging of the disc as storage conditions, handling and media construction have more bearing on this

Thanks for your opinion about the aging of burned DVD's
Do you have any idea about the aging of DVD+-R's compared to the aging of DVD-RAM's ?

---------
By the way did you read thes studies on aging made by the GIPWoG:
"Government Information Preservation Working Group"
http://www.itl.nist.gov/div895/gipwog/index.html

Text of their report published on december the 9th 2004:

The first scientific proof that the new "16x certified" dyes are:
less tolerant to laser power and
- less stable for conservation
than the older 8x and 4x certified dyes
has been published in extensive tests made for the german c't magazine
To see that you have to follow the + marks for
"PowM" (power margin) and
"Stab" (climatic stability)
 
in a post by "MediumRare" summarizing the tests:

Yes, I believe this is superior rather than waiting too long, as the disc is clean/no scratches, fingerprints (for people who mis-treat their media). The laser heats the dye, burns the pits, and is cooled almost immediately (characteristic of write-once dyes), so as temperature straight after the burn is almost non-evident (in fact, the heat you feel off discs is from the drives temperature itself/centrifugal force, not from the actual laser reading/writing).

Ok .. yesterday I bought a PS2 with modchip ..
I was told that I should burn games on X2 speed when I burn then in order to get less pressure or something on the eye in the PS2 console ...
is that true ?
should I really burn at x2 speed ?
also, what media should I use ? DVD-R or DVD+R ?
and another question .. I just noticed that the verbatim x16 dvd-r and dvd+r that I bought a week ago .. can be printed on them .. theres a white thing on top of them, I just saw it, didnt noticed it when I bought them .. what is it sayin for me ?
can I burn on them normally ? or should I get special DVD burner for them ?
