What TV shows have only had a few seasons, but not their entire runs, on DVD?

There’s an Australian series called The Games that I think is brilliant. The whole run was released on VHS, but only the first series (season, to us Yanks) ever came out on DVD. John Clarke (of The Front Fell Off fame, co-writer and star) used to have a note on his website that they were working on a second-series release, but even that seems to be gone.

The four I’ve been waiting for are The Muppets, Sliders, Picket Fences,and Hunter
