Here's something interesting I found: Opening previews that appear on the UK release of Gonzo Presents Muppet Weird Stuff.
What I find interesting is that it has individual promos for two of the Muppet Video releases (The Kermit and Piggy Story and Muppet Moments) but not the others (that were released in the UK), while the openings to Fraggle Rock and Muppet Babies are included, but not clips from the episodes on VHS (in fact Jim Henson Video later put out a Fraggle Rock promo that was merely the opening, with an announcer talking at the very beginning).
It's also interesting how the promos for the compilations don't have an announcer. We just see a few random clips. No guest star clips, either. It's almost like the promos for Sesame Street videos that Sesame Workshop posts on YouTube. Some of the clips and editing is odd; For The Kermit and Piggy Story, we get a clip where somebody asks Miss Piggy if she works there leading to her karate chopping him, due to her just being fired, but not any clips where the firing is obvious. It'd be confusing to those who haven't seen all the backstage scenes. And for Muppet Moments, we get a second of the linking footage that leads to Sax and Violence. Odd editing!
