My bro just got himself a new nec3500a from newegg today along with some 8x sonic media from shop4tech.Anyway heres the deal.He tried copying a full dvd with nero.nero was saying he burn speed at 12x but the disc took almost 13 minutes.Could this be a media problem or firmware problem ? i told him to run nero infotool to see what the media 1d & see where but nothing should up. it just said N/A.
