So many numbers and letters!

[L0cxs]

I am buying a LiteON burner and need some info.

I am very clear on how all the SD 2 protections are only burned by certain burners, and i know the LiteON burns most of them. But the problem is which one burns all of them? I also See LiteOn32XXXXXX. What does it all mean and which one do i want?

Sorry about the ranting, but its late and i cant type very well.

Last question. I promise.
What is firmware? Which version do i want? I have heard that only some versions of it work and others dont.

Can someone please point me in the right direction.

Again, im sorry about the ranting.
