Yeah, I hate that blu-rays have to have the bookmark function built in, and various shows were put on BD without it.Besides, the menus are of the overanimated clunky variety and the authoring doesn’t include saving the playback position. I wish they’d do a proper 2020s release making TOS-R nothing more than an extra.
In the "old" days of DVD, my DVD player could save my spot on any disc I played, since it was a feature of the player and not dependent on a function of the disc.
