Plextor PX-716a Problem (again) with Nero

My Plextor doesnt erase dvd±Rws!
I get always noseekcomplete,energiekalibierungsfehler!

very mysterious things go on!
every time a new Prob!

I think there are issues with 716a and RW media - On almost every RW I’ve created in another drive, I’ve had to do a full erase on them with my LiteOn before they work, otherwise the drive craps out with a similar error.

Once the drive is working from a ‘virgin’ RW 'tho, it usually works okay for me…
