Install DeVeDe and Brasero, and use them to make DVD player compatible DVDs. On Fedora, you need to enable the RPMFusion repostiory in order to install DeVeDe. If you haven't already done so, add it to your system.
Where can I go for help? In the past, with older versions of Linux mint, I’ve never had any issues creating ISO images and DVD’s. Now, I have nothing but issues like: 99% full project creates a 3.3gb ISO, FF to next track/file goes back a track, and others. Literally I can’t find an DVD creating app for linux that just works anymore. I’m using Mint mate 19.1 and mint mate 21.1 on a lenova X230 thinkpad. 2009 were the last versions of ubuntu / mint that everything worked without issues.
