I have used the 4570 with Verbatim DVD±R at 16x to burn data discs. When I check these discs after I have burned them using Nero CD/DVD Speed I got very high PiMax (DVD-R =600 DVD+R=200) and high PifMax (DVD-R=44 DVD+R=13). I have to use the NEC 4570 for checking the discs. But when I look on the results of the burner preview then the drive had very good results using this discs. They are the same that are used for the preview. (MCC003 and MCC004 are the disc manufacturer).
So is my drive not ok or are there any other possible reasons for that bad result of my drive.
Thx, Dino Dini
