growisofs giving I/O error

["[KS]" <lists04@fastmail.fm>]

Hi all,

Off recently, I have been getting the following error when I'm trying to 
 write a DVD (from image or directory) using growisofs. It always 
occurs at around this point, i.e. at around 93%-95%. This was the 4th 
coaster DVD I got.

What could be reason that this is happening? Any clues?

Thanks.
