Because Ihas drivers are the only one who can write new DVD-DL media for Xbox360;
The new iso files reach 8.800Gb and the DL medias has only 8.50Gb. so, a guy made a Custom Firmware that is only compatible with Lite-on drivers, so the driver can write until the very end of the disc and burn the max of the media.
The firmware name is “iXtreme Burner Max firmware” .
So, because of that, lite on driver’s will sell like water on the desert ._.
