Your conclusion is logical. However, as I said, I have never had problems with the non-Verbatim media I have been using (not just TY media). The fact that I have never had a problem, by itself, doesn't mean that I couldn't start having one now if it is the burner but on the other hand, what is the chance of having a new problem with a burner that coincides exactly with starting to try to burn with a different type of media? Now add on to that that I have just burned 10 flawless TY disks today with no issues and have also since burned a few test runs on what is generally considered so-so Acro +RW media as well and have not had any issues with it.
Again, the fact that so many people have had no problems with Verbatim media is a sign that the unbalancing factor in this equation is me, my configuration or my burner. Despite this, I am going to throw a wrench into the works. There is one factor that has not been mentioned: My absolute sh1te luck!!!!! Now, illogical as that seems and despite the fact that there is no sensible correlation between "my luck" and Verbatim media, the fact is that I keep ending up with spindles of Verbatim media that are of questionable quality. To put "my luck" into context, I'll give you an example. Ever play Civilization (the board game)? Remember those cards that had "Calamities" associated with them? Yeah.....my friends used to enjoy the fact that I would keep picking up full hands of almost nothing but calamities. They were amazed. "My luck" certainly doesn't end there. Anyone that knows me is in awe of the things that happen to me. People around me generally learn to have significant respect for the black cloud over my head.
Enjoy your Vodka and don't spill it or break a glass
