LG 4120B - Verbatim DVD+ 16x will be burned with 4x
I have the newest firmware A115 and Nero 6.6.1.4

Does anybody have similar problems?

Check if DMA is enabled. Sometimes windows reverts to PIO mode without any warning

Probably you use MCC 004 media, which is not supported even by the A117 firmware, so it is burned with the 4x default strategy. You could use MCSE to rename the MCC 003 media code to MCC 004, which enables at least 8x burning and also voids your warranty.

A117?

Where can I get this firmware?
