I LOVED this show. It was White Dwarf. The dichotomy in technology (rustic setting with periodic pieces of high tech) is a common thing on frontier planets in science fiction.
The description from Wikipedia:
In the year 3040, New York medical student Driscoll Rampart (Neal McDonough) is completing his internship on Rusta, a rural planet which due to it being tidally locked to its primary, is divided into contrasting halves of day and night with the halves separated by a wall. The two sides are involved in a civil war: The day side containing a Victorian-styled colony is at odds with the night containing a medieval kingdom. The differences between the two cultures leaves Rampart in a state of wonder. Rampart arrives from Earth for a six-month stint at the Light Side clinic run by Dr. Akada (Paul Winfield). Rampart's ambition is to eventually set up a private practice in Manhattan on Park Avenue.
