In the late 90's or early 00's I remember watching part of a movie or tv show on a weekend on directv. I think it was probably on the sci-fi channel. I don't remember if both the husband and the wife were scientists, but I recall that the husband was working in some kind of genetic engineering field. He created a machine that looked like a glowing coffin that would radically alter the genes in your body and create a designer body for you. He began to play around with this and turned himself into a woman. At some point in the plot he is at a bar, as a woman, and meets an attractive man with blue eyes who reveals himself to be his wife, who used the same machine to become a man. Probably not much to go on, but I would like to see the whole thing again now that I'm an adult to get a better grasp of wtf was going on.
