k3b
I won't be surprised if only this program can burn those discs on Linux.
It's a KDE application but it can be installed in any flavour of Mint without a single problem in my experience.
I've been using it since my day 1 on Linux a long time ago and 99% of time not on KDE. So don't listen to crap like "it will pull thousands of kde libs to molest your virginal Cinnamon".
My advice is go to k3b forum and ask for more specific instructions
about burning M-disks (don't ask em how to install k3b properly on Mint, ask these questions on this forum if you need to)
