Hello!

I am new to the forum,and i was wondering if you could help me,as i am a newbie in DVD burners.

I bought recently a Pioneer 107D.Now,i had 2 issues.First ,3 Verbatims DVD-R 4x (MCC) failed.Or to be more precice,in Neto DVD Speed i got an unrecoverable error.These 3 Verbatims were out of 15 (2 packs of 10 each).I still have 5 to burn.I have the latest firmware 1.12 and Nero latest version.Now,i used to trust blindly Verbatim CDs.Can they be defective or should i worry about the burner?

I ask this also because of the graph i get from Nero DVD speed.The line is always erratic and makes me wonder...Is it normal?

Thank you in advance
