To me, Darkroom sounds like it would be a copy of Rod Serling's Night Gallery, and the third one I don't know. But I definitely remember the very short-lived Phoenix. I only saw the pilot and two of the 5 episodes when it aired on ABC. I didn't see the whole thing until Sci-Fi channel had it back in the channel's early years. One thing I liked was that an episode took place in the general St. Louis area, near where I'm from. Since the main character was searching burial grounds, it brought him to the Cahokia Mounds area.
A few years ago, I got a dvd of the series from someone on eBay. Definitely not high quality, as it was made from a VHS tape. Seeing as how another 80s scifi show 'Voyagers' had a commercial dvd release, maybe The Phoenix will get a shot. Hell, even that annoying 80s show 'Small Wonder' gets a Season 1 release in February.
BTW, season one of Tales From the Darkside is on dvd also.
