i've used this plugin a lot, and it is nice, but a bit hit-or-miss. it analyzes all episodes of a show to start seeing a pattern in the beginning of shows, or checks chapters which my files rarely had. works well for most shows, but if a show has unique intros for every episode, it doesn't really work. also had trouble with 100% consistent intros, but i never really figured out why that happened.

kind of a 50% solution, works a lot of times but a lot of other times you still end up scrubbing. (also consider that if you install this plugin onto a large existing library, it's going to take a considerable amount of compute and real-world time to do complete it for every show).
