Looking into hardware, what excatly dvd device you’re using? External dvd or dvd player box? I never thought dvd player box would work thru general computers due to proprietary chips inside that only can work with television or monitor, so I never wasted my time trying to. You can order external dvd or blu rom from newegg, they have so many, then plug into your laptop to see if that works. They’re not too expensive. You might want to find one that’s more popular with linux users.
