I have the si fi one. I love old kinescopes so I like much of this anyway. I really like the Mill Creek stuff. I have lots of their things and I'm glad that they reissue old TV.
In The Adventures Of Superman one of the fans fav. programs, The Stolen Costume suvives only in 16MM. As for HGWT, many of the openings and credits exsist only in 16MM. Shows were edited for syndication and sometimes these elements were lost!
