GSA-50N and GSA-22N Can Bitsetting be set for dvd+r and dvd+rw?

Can Bitsetting run for dvd+r and dvd+rw for GSA-50N and GSA-22N ?
Need to know before I buy if bitsetting can be enabled?
Anyone who has either of the two LG burners, please reply.

DVD+R and also DVD+R DL yes, but DVD+RW not IIRC.

I have a H22N and it has bitsetting DVD-ROM by default for DVD+R / DVD+R DL. You can change to normal ( DVD+R ) using normal burning programs like Nero or Imgburn.
