K3B/growisofs – more than 50% of space will be *wasted*!

While trying to burn a 900mb ISO file on a dual layer DVD, I got the error. “more than 50% of space will be wasted! use single layer media for this recordiong”. I avoided it by burning a multi-session DVD (e.g.: growisofs -Z /dev/hdc -R -J /home/user/files/*). Another solution would be to add more files to the iso (using isomaster) until it is more then 50% of the capacity of a dual-layer DVD.

Debug output:

growisofs: 7.1
