Plextor PX-755SA issue

Hi,

I have a Plextor PX-755SA and I have noticed that lately I am getting circular shaded rings on the burned side of DVDs. I think that those are resulting from re-calibration of the laser while burning but I am sure that the drive behavior was not like this before. I suspected that Powerec is ON but although it was switched OFF and I re-switched OFF from both Plextools and Nero those re-calibration pauses still result. Both DVD-R and DVD+R are effected. I am attaching a test disc result for a DVD+R.

I am running Plextools v3.16 and Nero 8 on Windows 7. I have also tried with Nero 6 on Windows XP (dual boot system).

I am suspecting that Powerec is not switching OFF.

Can someone help, please?
