there are episodes filmed on ships. Quite a few featured scenes shot on the real boat mixed with fake studio work. They did more the first half of the season. The Richard Mulligan as a novelist segment of his episode was one a boat while the other two were studio.
for anyone complaining about the lack of extras, I recommend reading this: ''The Love Boat'' flashback | The Love Boat | Television News | TV | Entertainment Weekly
It was interesting to see that three different directors did the various storylines during the show. Anyone have a clue if they shot concurrently so that it shortened the production schedule? seeing George Jefferson and Aunt Esther as a married couple was worth this boxset.
I do have a review copy of the set for my quickstopentertainment write-up. I get the idea that Paramount now puts that disclaimer on all their DVD sets just to make sure nobody can sue them for "incomplete episodes" since it might be missing a second or two from the broadcast original version.
