When I turned 18 the first thing my friends and I did was go to Porn shop. Nothing really looked interesting, I had never seen a porn before, and to be honest they all kinda creeped me out. I wanted something 1970's, something with a story. Eventually I just settled for the one film that didn't feature a midget or a animal on the cover. This movie had no story what so ever, you put it in, selected play on the DVD menu, and immediately you were bombarded with nearly two hours of sex, with no talking other than the usual porn lines (give it to me, f*** me). I only watched it once, the first night I bought it, but the next day I decided to watch the 'behind the scenes' features (which to me seemed more interesting than watching other people do it, and much less depressing). The main guy in the film, Evan Stone, was very candid, extremely funny, and had very high energy. I can't look at him and not think of that first (and only) porn film I purchased.
A few months later I moved across the river from Vancouver to Portland (North Portland, Portland Blvd. and Denver Ave), and I purchased DirectTV's largest package I could afford. So, one night I am flipping through the movie channels and I come across a film called "Genie In A String Bikini" on Cinemax (of course), and there he is again, Evan Stone, acting in this soft-porn flick. Then a month later I saw Showtime was airing the adult film awards, and I turned it on cause it sounded interesting, and I kind of wondered what the name of the awards were (instead of the best actress, they have 'best female shower scene'). That was 2004 and Evan Stones won best actor.
The original poster said the Star Trek porno starred "two dudes i have never heard of." I assumed that the OP most have seen or heard of some people in the industry to make that comment. Really, besides Evan Stone (and Ron Jeremy) I probably wouldn't recognize a single adult film star on the street. To be honest, the Star Trek theme is pretty simple to make. They are exploring lost planets, find one that is all women who need males to mate with. End of story.
