Event though DVD Studio Pro is deprecated, Adobe Encore CS6 is still kicking on Mojave and with it the ability to author (relatively simple) DVD and Blu-ray Discs.
Check this previous post for how to download Encore CS6. You cannot install Adobe Media Encoder CS6 anymore though, so you are loosing the ability to encode Dolby AC3 audio with Adobe. Fortunately for us Mac users, we have Compressor for that!
And by the way DVD Player is still there on Mojave, only buried under: System/Library/CoreServices/Applications.
