>Description:
Some pioneer dvd burners wont burn a dvd correctly if the data is more than a 
certain size. dvd+rw-tools fails when trying to close the disc. It is a well 
known problem and appears on many mailing lists.
>How-To-Repeat:
Use growisofs with a fairly large size of data to make a dvd.
>Fix:
There is the following patch floating around the internet which helps.
