@slash i don't own dvds to rip so i just get whats out there :blobcatpain:

most of these capabilities aren't actually used. yt-dlp can embed youtube chapters to mkv, including sponsorblock segments, but you have to ask it to. most of the players understand simple chapters. i think VLC supports DVD chapters in DVD files but i'm not sure if it understands them through matroska.

(MKV does support pulling a DVD with the menus and all special features but nobody actually does it)
