I acquired new BenQ (1620 Pro) yesterday, and flashed newest firmware in it. This far i have only tried one dvd-r brand: 01NE (Lead Data, LEADDATA01).
I'm not sure how to interpret dvd-quality test results. What exactly PI errors mean? The seems to be very high and yet Quality Score remains nearly 100. And even if Quality score shows something like ~95, DVD-Reading speed has huge fluctuations.
It seems that every time when i run quality test, I'll get different results. Yesterday I ran same test, but PI errors were sky high, constantly in 500 but Quality Score remained about in 95. Unfortunately i didn't took any screenshots.
Btw, what "No additional sense information" means?
I have attached two test results.
