I'd still like to figure out why I can't burn on my DVD drive, though, so if anyone has any ideas, I'd love to hear them. I'm thinking there must be an entry in a configuration file that needs to be changed, but I'm still too new to admin stuff to know which it might be.
I think, it is buggy software (i mean Brasero). The same error i got, when trying burning dvd with xfburn. You can try cli program "growisofs". Here the short tutorial for using it https://community.linuxmint.com/tutorial/view/1089.
