Okay, believe it or not I actually have this. I bought it (from Amazon.com) several years ago - maybe a year or two before they started releasing either series on DVD. Never bothered watching the animated movie, for the record. It looked too embarrassing. I think it's in a closet somewhere :-) I don't recall exactly what the extras were, but I do remember not being overly impressed. I can dig up the discs and check though, maybe. I moved all of my DVDs out of their original cases and into CD binders, so I'm not sure if I'll be able to tell which is the version of the movies released with S1 and which is this set. There might not be any difference.

Anyway, I think this was one of those cases where they released a few episodes of a series on DVD to sort of test the market and see if people would buy it. These guys probably just have lots of them left over now that people can buy the whole series.
