Sorry about the negative welcome to our forum. :sad:
rolling56 was helpful though.
First, position of layer break has nothing to do with firmware. Any drive able to burn dual layer discs is also able to burn with layer break exactly where you want it.
Buying a new drive wont change anything.
I don't know anything about how to copy X360 discs, but I know how to put my layer break exactly where I want to have it. My favorite tool for this is PgcEdit and you can start to learn about it by reading this guide.
BTW, this is a software problem so you maybe better check out our software forum sections.
Edit and off topic
Thanks Liggy for removing serial.
It's just me or shouldn't whole chef's post be removed.
