Bit-setting available for GSA-5163D? (as DVD-ROM)

Guys, I know I seen this addressed here somewhere before I actually bought my new drive, but now I can’t kind jack!!

Please point me to the right thread or share some light on this?
I want to enable automatic book-setting to DVD-ROM, how and what do I need to do with this drive to make it happened? This is my 1st LG drive and I use it as a external to my Dell D800 laptop.

Also, I’m still trying to see whats faster and better, the USB 2.0 or the Firewire using Copy-Disc-To-Disc? What have you tried?
