I tried to write 1 single-layer DVD image (Centaurus beta) onto a double-layer DVD+R (I had no single-layer DVDs), but this was impossible in brasero in Simply Linux 6.0.0 beta 2011-06-20 (brasero-2.32.1-alt2.M60P.1): the backend said that much space will be wasted and didn't want to proceed. And I saw no option in the GUI to force this. It would be nice if there were an option in brasero's GUI to force writing onto double-layer DVDs, even if the image is small.
