Hacking How do I change booktype?

[FireFreek]

So yeah, right now I only have DVD+R discs, and I can't buy any DVD-Rs, and I hear it will all work fine if I just change the booktype in ImgBurn. So I loaded my .ISO and I looked in the settings and I saw under Tools>Drive>Change Book Type.. that you had to choose your tab with your drive brand, and then change the booktype. However, my brand wasn't listed. Mine is Matshita. Also, is there any guide on doing this? If not, there should be one.

EDIT: Nevermind, turns out my drive doesn't have that option. Someone delete this thread
