Way back when I still lived at home, my family had a little game, someone would put in a movie and the first one to guess which movie it was "won." I could often do it from the previews. DVDs spoiled this with their menus. Well, most of them did. Some of them do just start playing the film (or start at the previews).

I recently ripped my whole DVD collection to my NAS because, well, optical drives are going extinct. And I noticed some patterns. DVDs of contemporary movies from early in the format's history were often special events. They had specially designed one-off packaging, lots of extra features, extravagant menus, etc. As you went later in the format's run, packaging became standardized, and especially older pre-DVD movies that were being re-issued on DVD would often just auto-play the movie when inserted. They often had menus that had no animation or music so you could chapter select or toggle the subtitles on but you'd have to stop the movie to see them. Also, TV shows on disc suffered way more from disc rot than movies, I'm guessing the discs themselves were cheaper/worse.
