DVD-Audio/-Video hybrid should prefer DVD-Audio
I am using VLC 3.0.17.4.
I have some DVD disks containing both a DVD-Audio and a DVD-Video structure. When I play such a disk in VLC, the DVD-Video is started. The whole point of having both structures on the same disk is to provide merely some level of fallback to pure DVD-Video players which don't understand DVD-Audio. The DVD-Video part is not meant to be played back on players that do understand DVD-Audio. So the DVD-Audio part should always be preferred over DVD-Video when available.
