@minaelromany: We're having a bit of off-topic fun here in your thread.
If you don't want that then just let me know (e.g. by PM) and it will be cleaned up. :flower:
Are you burning so many discs that you don't have time to verify each and every one? I always verify any disc that isn't just made for testing, usually with the "verify" feature in ImgBurn and sometimes with the "verify" feature in Nero Burning ROM.
For every new combination of media, drive, firmware, burn speed, and setting (e.g. SolidBurn) I make quality scans and TRTs.
For most discs I perform a DQS at 8x in my BenQ or at 16x in my LiteOn 165P6S in addition to the verification, in order to detect ugly PIF clusters or other problems. And I hardly ever burn DVDs faster than 8x because I have found that burning faster will increase the likelihood of a bad or mediocre burn in all drives that I have, although 12x burning is good most of the time.
I don't think that 8x burning wastes any time for me, because that saves me from throwing away and redoing burns that don't meet my personal criteria for being acceptable.
I do believe that high-speed scanning is good for making keep/discard decisions, but the PIE/PIF values in high-speed scans are not necessarily a worst-case scan - in some cases, especially for LiteOn drives, I find that scanning at low speeds can produce higher PIE/PIF and 1x scanning is often the worst scan on my LiteOn 165P6S.
