I tried ubuntu 17.10 (live) and it seems thing changed.
When I try to test an ISO file, in the right click menu there is no more a "Write to Disc..." option.
The closest thing is "Open With Disk Image Writer", which then ask for the destination drive, but does not allow the DVD unit (there is a blank DVD+RW inserted, displayed as so on the desktop) to be selected, it is greyed out.
Even if I try a smaller (391MB) ISO file.
