I've been burning a lot of DVD's lately and i am getting this error while trying to burn and image using toast 7. What could this mean? If i use disc utility it will give me a buffer underrun i believe is what it said. It just started getting bad today. I have to try 10 times occasionally before it will actually work. in toast it say writing lead in... and i can hear the drive speed up and slow down a bunch and then it gives me this error. Nothing is actually burned on the disc. It has a hard time reading discs also that have been previously burned also. I hope it doesn't mean the drive is going out. Any help would be greatly appreciated.
