What are some ways to identify the dvd chipset?

[element72]

I'm just interested in the d2c, d2c2(if im not mistaken), and d2e chipset. If one of those is not written on the chip, what is the alternative? I remember reading something about looking for an extra metal piece in the back of the dvd drive.

It's always on the chip, there's no other way to tell.
