Poor burn on Liteon 411



Hi, this is my first post on this forum.
I have recently purchased a liteon 411s and flashed with the FS0J firmware.
I started to burn some verbatim DVD+r (MCC) certified at 4x at 4x, and they should be quality media.
But i get strange result from kprobe, a high PI error count and regular high spike, and they often won’t play in standalone player…
There is a problem? I should change the firmware?
