I need help. I need to burn a DVD DL Under system profiler for the cd drive it clearly says that DVD+R DL media is supported. which is what i have A Memorex DVD+R DL 2.4x dvd. But when i try to burn onto it in Disk Utility it just fails and gives me this message "Unable to burn "disk3" - The device failed to calibrate the laser power level for this media.." Why is it doing this? Is something wrong with my superdrive? It burns cds and plain dvds fine.
