I have a G4 with a combo drive and want to fit a DVD burner, however I want it to be compatable with idvd etc. I have looked into patchburn and will go that way if need be, however some people have posted in the past that they have put in a 3rd party drive and it worked ok without patchburn. I am wondering if this is because these are models which Apple use - so if I knew which models were used in new G5's I could maybe fit one of these? So, if you have fitted a DVD burner which works with the i apps, can you post the model and perhaps some of the G5 owners could post the model of their burners? thanks.
