Yep, SOAPnet is currently airing episodes from February 1978.
Nancy Barrett was on from July to August 1976 as Faith Coleridge #2, and she appeared in 9 episodes. Unfortunately, both she and the show felt she was miscast and they mutually decided to part ways. Catherine Hicks (now on 7th Heaven) is currently playing the role on the SOAPnet reruns.
Two screen caps of Nancy on RH can be found here.Donna Wandrey played Dr. Myers for two episodes in March and April 1977. Dr. Myers helped Delia Ryan with the miscarriage she was having at the time.
Kenneth McMillan, who appeared in two or three episodes (?) of DS, played Charlie Ferris in a few episodes of RH from 1975 and 1976.
As for Craig Slocum, I'm not too sure if he really plays Lou. Lou hasn't changed portrayers since the start of the show, but the one time Lou
was listed in the credits, they stated that Carlo Grasso was playing the role.
There are a lot of connections between RH and DS behind the scenes. For the show's first ten years on the air, RH was taped in the old DS studio.
Robert Costello, who produced DS' first three years, also produced RH's first three years.
Lela Swift was the main director on both RH and DS. She directed both of the show's first episodes along with their last episodes. Henry Kaplan later joined the directing team at RH during some point in the mid-to-late 80's.
Sy Tomashoff also designed the sets on RH until the early 80's.
Ramse Mostoller was the costume designer on both shows, while Sybil Weinberger supervised the music on both.
