Is that 'short film' that replaces the newscast from Four Feather Falls?

yes it is

There is rather too much similarity between this episode and "Robert to the Rescue". In both of them, Professor's Matic's activites lead to the discovery of a planet, and the inhabitants of both planets have an obsession with privacy.

Professor Matic turned on the Ultrascope and they instantly saw the surface of a planet. How is it that he could immediately identify it as being Utopia? No one had ever seen it before. And how could outsiders describe it as being "the most beautiful planet in the universe" (which, in my opinion, it wasn't) if they've never seen it?

Why didn't it occur to the Utopians to hang out the outer space version of a "Do Not Disturb" sign, if they were so touchy about their privacy?

I could comment on the supposed intelligence of beings that trade their women for eternal life, then start salivating over the first alien female that comes their way, but I think that it speaks for itself.

I don't know how Venus managed to keep from bursting out laughing when Privator came in and addressed her in the exact same words as Perfectos did. (And unless those two were the only Utopians around, I could see a mass free-for-all breaking out, unless they decided to keep Venus hidden.)

These superior beings also seem unaware that a light year is a measure of distance, not time.

I found that the name of the planet is Nutopia, not Utopia. I guess that the ear hears what it expects to hear.

I wonder if Perfectos has spent any of his eternal life trying to cure his bald spot?
