After studying vorrangegangener reviews I've noticed that more LG burners seem to have problems with these blanks. I myself had to burn two 10er spindles and could on my NEC ND-4550 without the Committee so far. Even reading the recorded blanks happened easily in my DVD player (Kenwood) and my PC drives.
Conclusion: If you own a LG burner should rather stay away from these disks and Verbatim (highly recommended if not for the price would) change. For NEC burner the latest firmware these blanks are recommended but if only for the price.
