My DVD playback issue is not specific to Libreelec. I attempted to play the disc with OSMC (Kodi 18) on my Raspberry PI 3 with the same results, hangs going to main menu. Disc worked fine on the laptop with handbrake.

Sounds like a kodi issue. Can you reproduce with an Ubuntu build? That will probably have a better chance of getting the right devs to look into it.
Open a track ticket if you can. 

 Will do. Just installed Kodi 18 on my Bodhi Linux machine. I will have to wait until I come across another disc. I sent the problem one back after watching it on the laptop in VLC.
