Overburning with NEC

The new version of NERO supports DVD overburning. Now my question is can overburning be done on 3500. Also can overburning be done on both +r and -r. Has anyone actually done it and did you encounter any problems doing so and finally does it matter on the media quality? Thanks

dont know but it probably wouldnt be worth it, last time I tested my 3520 the overburn only added like 3 minutes with regular cdrs
