Dragon Burn has worked well for me.
dozens of DVD and CDs burned just fine.
No reservation in recommending.
I had a problem with my System and needed to back-up apps and files, having decided to reformat the drive. Toast kept getting an error message and failed to do the job. Dragon Burn got the job done. I suspect that the nod went to Dragon Burn on this because Toast had been on the system and perhaps became corrupt in someway, and I could not find a way to correct that, no matter what I trashed and reinstalled. Dragon Burn was fresh to the system. Otherwise, I considered that Toast was making a call to the system that was rejected and Dragon Burn handled it differently. All useless speculation but such as it is.
No Hesitation to Recommend Dragon Burn.
