Hey guys, I got my mac pro about 1 week ago. I got the BTO of 2 super drives. Well, I just tried burning an ISO and when I put in a blank dvd it won't pick it up to burn the file. I have tried with Memorex DVD+R's and Sony DVD-R's. Neither will work. Now the weird thing is regular dvd's work, games, and even Windows 7. Also I have toast 10 and it will pick it up but when I choose ISO and drop the ISO in it, it then says it can't burn audio tracks or some warning. Anyway, can someone help me? Any help would be greatly appreciated!
