Hi guys, I've had the MBP since Jan. and at first when I burnt DVDs/CDs using the optical drive, no matter what speed I did it at, it would never burn it properly. Granted these were always OS discs, but when I burnt them from my PC it worked fine. So I just assumed that it was a problem with the OS Iso's and the optical drive/media. Now though when I try and burn a music CD, it gets to writing lead in/out and it always fails, leaving the last few tracks unreadable by my car CD player. I used itunes for writing, and Toast (full) when I was writing the OS CD's. As for the brands, one is vertibam, and the other was a PCworld unbranded. Anyone got any ideas, are these brands not supported by the MBP's optical drive?
