I purchased a NEC ND-2500A several weeks ago and have been able to successfully burn a handful of dvd+r fuji media at 6x. Recently I tried a generic “silver top” 4x dvd+r media that can be found at shopampm.com - http://www.shopampm.com/product_info.php?cPath=56_114_115&products_id=275. So far I have tried to burn data and videos at 4x and max 6x and have created dvd’s that are not readable by the 2500 writer itself, my computer’s dvd-rom drive and my dvd video player. I tried a firmware upgrade to offical 1.07. Still, no success. Anyone have any suggestions?
PS - thanks for all of those who contribute to this great site. I’m a newbie and you’ve all been helpful in my burner selection. Thanks!
