Description of problem:
growisofs will refuse to burn data to a dual-layer DVD if the data is less than 50% of the disc's capacity in size (4GiB), because the extra space on the disc is "wasted."

Version-Release number of selected component (if applicable):
7.0

How reproducible:
Every time.

Steps to Reproduce:
1. Attempt to write less than 4.0GiB of data to a dual-layer DVD (I used k3b as a frontend to growisofs)


  
Actual results:
growisofs complains that too much space will be wasted and exits immediately

Expected results:

The burning continues normally


Additional info:

This is really kind of absurd.  I have no other DVD's but of the dual-layered variety, so I was stopped from burning a disc because someone else decided for me that it was too wasteful.  It's almost certainly the same amount of plastic as a normal DVD...

Here's a patch for growisofs to remove the limitation:
