It seems that one area that hasn't caught on to the idea of TV on DVD is the educational channels. There are tons of great series that haven't made it to DVD. Those that do are often released piecemeal, and the ones that get season sets are often outrageously priced (Mythbusters, I'm looking at you!) And many of these shows aren't offered through regular retailers, so you can't even get a competitive price. Here are the shows I think need a DVD release most desperately Connections - A James Burke series that demonstrates that history isn't a simple linear narrative, but a complex web of chance events, and if some Roman hadn't stubbed his toe two thousand years ago, we wouldn't have plastics today. The sequel series, which are no where near as good as the original, are on DVD for $100+. The Day the Universe Changed - Another James Burke series, similar to Connections but focusing on scientific revolutions. The Human Animal - Based on Desmond Morris' book The Naked Ape. Morris examines human behavior not from the point of view of an anthropologist or sociologist, but as a zoologist viewing humans as just another species of ape. The episode on mating habits is twenty times more interesting than HBO's Real Sex series. The Wonderful World of Dung - Not a series, but a one-off documentary on excrement. It simply has to be seen to be believed.
