I am burning a folder onto a DVD. The folder contains subfolders which have images and video files.

I am burning by dropping the folder onto a blank DVD on the desktop, opening it up and clicking "Burn", then using maximum speed to burn. At the end of the burn finder brings up a message saying that it couldn't verify the burn, and ejects the disc.

If I insert the disc back into the Mac, I get a message saying that it cannot be read.

I have done this 4 times only one disc has worked. All four times were done in the same method. The discs are Verbatim 4.7GB 16x DVD-R

How can I complete the burn successfully?
