Looks like my installation is also broken, not only the dvd writer part, something really messed up by dnf..... But... No clue why burning *any* media is impossible, because when the process is started looks everything nice - it's just torns the drive when needs to be finalised. Worse thing is that drive bay door keeps closed - unable to eject - because the thread can't finalize the writing, disk remains empty, and NO app is able to write anything. When I tried to kill the tread, interestingly the app closes, but the drive keeps spinning, and staying repeatedly in finalizing phase, till I power off. Really scary, when the drive loudly scratching repeatedly positioning back and forward....
