I don't know if you remember this series, but it was one of the first with arc's and also to use green screen shots in the main - using Amiga's for the early graphics!
Great series which I luckily got for Christmas - had been watching this for some time and is usually mid 50's to 70's.

In 1994, Star Trek had to take a backseat to a new kid on the block, science-fiction series Babylon 5, created by Michael Straczynski. In a nutshell, it's the 23rd Century and the Babylon 5 space station has become an interplanetary peaceful negotiation centre. Humans and aliens attempt to settle differences in a reasonable fashion here under the stewardship of President John J. Sheridan (Bruce Boxleitner), which makes for some fantastical plot arcs throughout its five year run.
This stylishly compact yet comprehensive box set contains every Babylon 5 episode ever made, the series Crusade and all six Babylon 5 feature films with extras, plus the brand-new feature The Lost Tales, which has never been shown on television.
