Hello. I've just had a matrix infinty chip put in my ps2 and want to download the latest firmware upgrade for it. It says that to burn it to disc i should use Nero or equivilent. I have an apple mac powerbook g4 and when i try to put the burnt disc in my ps2 to upgrade nothing happens. Am i thick? I am new to this. the disc has been burned using the software pre installed. An idiots guide would awesome.
