LG Burner: striped lightscribe print result (LG GSA-H50L)

[qanda]This thread is about the LG GSA-H50L. Click here to see full specs[/qanda]Hello,

i have 2 lightscribe burners in my PC.

The LG HL_DT-ST DVD-RAM GSA-H50L doesnt print a one-colored plain disc, it makes stripes on it.

Lets have an background image with a one-colored area, the ASUS Burner prints it in one color, but the lg creates stripes arround. it looks like the lightscribe laser doesnt position correctly and prints a darker and a lighter circle and so on…

Is there something to do, or should i have another burner?

Best regards
