And from the growisofs man page...

-overburn 
Normally DVD media can accommodate up to approximately 4.700.000.000 bytes (in 
marketing speech 4.7GB). In other words a DVD can contain about 4.377 GiB or 
4482 MiB. Growisofs won't start without this option, if "overburn" condition 
appears to be unavoidable.
