I've been through with my LG burner tested at brands and read out the data quality with PLEXTOR PROFI tools. The results at VERBATIM are simply perfect. The decisive factors are also long-term tests. I still Verbatim Bluray blanks that still run today properly and have even seehr good readings from the 1st generation (about 3 years old). Other providers such as Maxell (Ritek), Sony and especially Platinium fall as significantly from !!! Now I have been experimenting enough. I'll stay with VERBATIM - even if the discs are significantly more expensive than the competition. By the way: I am burning with so NOT a Allerweltsprogi like Nero, but with free tools, which are clearly set better and more professional.
