Yes, they are showing episodes from seasons 1-5 that have not been released on DVD but these have been cut down to a half-hour. They are not showing all episodes from seasons 1-5. They skipped the very first episode of the series. I don't know why. Also, they are not showing these in any kind of logical order. They are not following original air dates or production order. It's kind of all over the place. From what I've read on MeTV's site, they are jumping around within the seasons. For example, first they'll show a season 1 episode from 1967 then the next night they'll show one that is half way through the season like a 1968 episode. I'm not sure if MeTV came up with their own episode guide or if this was provided by whomever is distributing the series. Either way it is a mess. The episodes that have been released on DVD as The Lost Episodes are also being shown (at least some of them), but again as half-hour versions.
