Memorex burner not book typing

I need some help from you. I just got a memorex dvd burner, model that shows on the os is dvd±ROM 510L V1. I don;t know if this is a crappy burner?? what do you think? i use shrink and Nero and with my old burner i was able to check the book type box, but now the box is checked and shaded out so i can not change it. When it goes to the burning stage, it does not say that the book type was changed. What am i doing wrong?

Use Nero CD/DVD speed to check booktype. Go to the Disc Info tab and it will tell you. If it is checked and greyed out in Nero settings then the burner should auto-booktype.
