My fiancee loves bollywood films, she’s got a dvd that has four full length films (in pretty decent video quality) on one disc. Considering tv shows usually have at most 4 hours of content on a single DVD, how is this possible? (Not double sided.)

modern codecs (= the way the movie is saved) can save a lot of space compared to older ones, at the price of a much lower compatibility with older DVD-readers.
think of it like older systems saying “okay, look, in this picture this part is black, this part is blue, and now in the next picture, this part is…” while the more modern version go “okay, so this part is black and until I say otherwise it’ll be the same in the next few pictures” (obviously it is MUCH MUCH more advanced than that.
there might also be other “savings” like no “making of” or other features, that otherwise take away disc space.
