Outer Limits was a classic. When I was growing up, a local TV station showed them every Saturday night and I was always watching. I didn't know they were on DVD now, I'd love to have them. I remember O.B.I.T., about an alien machine that was used for surveillance that had an even more sinister purpose.
I also liked Controlled Experiment, in which who martians named Deimos and Phobos used time manipulating equipment ot study a murder. The two martians were portrayed by Barry Morse and Carroll O'Connor. I could never see Professor Victor Bergman and Archie Bunker working together, so casting those two actors in the roles did give me a bit of chuckle.
There were also a couple of episodes with Martin Landau I enjoyed. One in which he plays a man from a post apocolyptic future who goes back in time to rewrite history by preventing the birth of the scientist who created the disease which devastates Earth, and another in which he plays a scientist who gets his hands on a piece of alien shielding technology with bad consequences.
I could probably list other episodes too, but there are just too many. I tried watching the new series, but it just wasn't the same. I don't know why, but the way they write them these days just isn't the same as the way they were done back then.
