I have the first two (season?) sets of this series on DVD, and I know a third one is coming out in August or September. Can anyone who is pretty familiar with the somewhat complicated format and history of the show venture a guess as to how many seasons or volumes might comprise this series of releases? I have tried to extrapolate as best I could from episode lists available online, and found it rather confusing since the show doesn't follow the standard self-contained single episode format. I had somehow come to the conclusion that the original show was three or four seasons long, but read somewhere that it ran in a reincarnated form for several more years. I don't know if that reincarnation was actually new material, or just re-organization of original material into new format. Any R&B experts out there who can help clarify? I was really hoping the DVD releases would cover the whole series in something like three to five box sets.
