I ran into an interesting problem today. I have some wedding DVDs that family 
& friends keep asking for copies of. I had been using K3b's "Copy DVD" tool. 
But I realized I could shave about 20 minutes off the time for each disk if I 
saved the image and reused it, instead of rereading the originals each time. 
I saved the images by selecting the "Only create image" option.

But when I went to burn copies, I ran into trouble. I had assumed that K3b 
would create an ISO image, and that I could just do a "Burn DVD Image" from 
it. I was worried when I saw the ".img" file extension that K3b used, rather 
than the conventional ".iso". I tried anyway, but the disk was unusable. Then 
I tried "New Data DVD Project", added the image file, but same result. I 
couldn't find anything in the K3b help, or on google.

So I went back to copying from the original. But after a successful copy, I 
was able to grab the actual command executed to burn the image from the 
Debugging Output of K3b (I wish all GUI tools would give you the command line 
equivalent like this, very educational). Turns out it's the growisofs 
command, with a number of undocumented -use-the-force-luke options. 

Anyway, I took a few minutes and turned it into a reusable script. I've 
attached it here for anyone who might find themselves in a similar situation. 
Maybe someday this missing feature will get added to K3b. In the meantime, 
enjoy.
