You might need to go to DVD for something that old.
There are advantages to getting owned DVDs, like the fact that they can't mess with the content later. Music licensing problems are fairly common. For Scrubs Season 1 in particular, they had to change all the music around for Netflix's streamed version. The DVD version, as far as I know, has the original music.
Dark Skies. It was x-files if set in the 1960s. But as it used music from the time, the classic music licenses have since expired and nobody is willing to pay enough to renew them.
Also, why in the world isn't The Twilight Zone (the one from the 50's) in the public domain? It already set up the genre, it has been exploited in TV with ads for sure for decades. Also, I think Rod Sterling is not alive since a good chunk of time, ditto with the producers. There no loss on torrenting that series. If any, it would help on sales on current sci-fi series.
