back in the day...back in the '70's/80's...a heck of alot of american tv movies/series were, in fact, edited down to become cinema releases overseas (the 1st, original Battlestar Galactica was one of the few i can recall that got a stateside edit/release)...this could be the origin of this monstrosity...

however...the networks often also edited down their own stuff for repeat viewings, figuring the audience wouldn't want to sit through the whole thing...or for ancilliary sales to secondary markets...like various lo-fi uhf stations of the day

when it comes to vhs/dvd/cd sales...the cretins-that-be often release the lesser version first...then resell the consumer the newer/bigger/better/badder version later...just to get your bucks: it's called 'capitalism'
