The difference in Drivers

[FMMMMM]

I have been using the plextor usb burner without any of the
drivers that can be downloaded from mtu. My computer has 6
usb ports and firewire. I have an atapi burner already installed in
my computer.

I think I missed something in the manual. What is the
difference between the mtu driver in the program, and the default driver. I have been using the mtu driver but I see a lot
of people being advised to use the default driver. I am thinking that this is one of the problems with error reports when I am burning.
