Verbatim at the moment the most reliable

I thought my burner is broken, dei double layer of Layer 2. ALWAYS had an error. (Read could not agree)
Last attempt of a new burner, the VERBATIM blanks.

And the result:
7 To date, blanks 25 ABSOLUTELY ERROR-FREE! - So not the burner. The blanks.

CONCLUSION:
At the moment the VERBATIM DVD + R DL seem to be the only reliable discs. (I really tried everything there is to blanks in the market. The faulty disks per spindle increased lately to appalling. In the end, when the low-50% scrap parts!)

AND 25 blanks for +/- 25 euros ..... could not be better.
