i have a dual 450 g4 gigabt ethernet powermac. last summer i bought a superdrive for it, a pioneer 109. it has firmware 1.4 on it. on the pioneer website the latest firmware for this one is 1.57 but when i downloaded the update it was only avaliabel as a windows exe. i have a pc i can use, should i remove the drive, put it in the pc, update, and put back in the mac? i dont if it would benifit any but i do have problems with errors while trying to make cds and dvds, usually about 50% it will burn right and the other half it will mess up. thanks!
