I hope that they will release Lost in Space on Blu-ray at some Point. I believe that the effects were all shot and composited on film so they would not have the same problem as Star trek had.
It sounds like you are referring to the TNG edited-on-video problem, not Star Trek.
UFO was a big hit with me. ... CBS did the show a disservice, putting it on a time slot that condemned it to death.
CBS wasn't the sole reason UFO was canned. While CBS had it on late at night (that's where I saw it as a kid) the show was aired on Saturday mornings on London Weekend Television and apparently not aired consistently.
