As I understand it, it's only the pilot show that will be appearing on the DVD. Many people confuse the pilot show with the first official episode, but they're not the same thing. The pilot show refers to the test show that aired before the "official" airing of the first show in November 1969. The only Muppets that were in the test show were Ernie and Bert. Remember when the format for SS was first conceived, the Muppets were originially only to appear as inserts between street scenes, like the short cartoon skits and "real life" films of animals etc. It was only after the test show failed, and they discovered that the Muppets were what really held the kids attention that more Muppet characters were created and were part of the street scenes, interacting with the human cast. AFAIK, while Kermit was in the first official episode, he wasn't in the pilot at all. I'll be very happy if I'm proven wrong though.
