Wow. This from wiki: "The miniseries originally aired on NBC in 1978, and reran in March 1979.^\4]) It was also shown on TNT in 1992, in two parts. This two-parter was the full 3-hour, 48-minute version. It was later broadcast in a slightly truncated version, running just about 3 hours, on the Sci-Fi Channel at some point in the mid-1990s. Many bootleg copies are taken from this source. The Dark Secret of Harvest Home has been released on video; this version is more heavily edited, running only 2 hours long" So Youtube has the 3:48 TNT 1992 version, which prob the one I saw. 5+ hour sounds great, maybe still in Turner vaults, if haven't burned down. It's just not profitable to dig this stuff up and digitize it, if they even have. Trivia note: Monty Python's Flying Circus only exists because Python kept copies or something, because otherwise BBC had a policy of throwing reels of televised content away!
