How to prevent/reduce DVD-R burning errors 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?

Update

The error codes is:


  This disc can’t be verified and might be unreliable. Try again using a new blank disc (error code 0x80020063).


I have researched the error and not a lot is written, just that I should try to close the finder window as soon as the disc starts to burn. This would seem like a very simple bug that Apple would have fixed by now.

I tried this and it didn't work. However I used a Verbatim DVD-RW 4x speed and the message poped up again, yet when I inserted the DVD it worked and all the data was on it.
Try burning the DVD at the lowest data rate possible - the higher the burn speed, the more likely you might get burn errors. 

I normally burn at 4x and have never had a problem. Though if your drive is having a problem, a lower rate will help (eg 1x)
