Ok, I have a pioneer 106. I occasionally see people talk about overburning certain media...How do they do this? Is it a firmware hack or a software hack? Luck? Luck, what are the combo's? Like what 2x can I buy and be able to burn at 4x with my pioneer 106? I know this has been discussed many times, but noone seems to give specifics... Anyone got any info?

EDIT: also 2.4x +r at 4x speed?
