probably a little of both
I would guess that the most immediate cause of his dismissal was for participating in homosexual activity, pornographic or otherwise (remember, you can't be kicked out of the Army for *being* gay - only for actual and verifiable homosexual acts. If a homosexual wants to join the military they can. They just have to be chaste for the duration of their contract. Look what Clinton's "don't ask don't tell" policy hath wrought).
However, based on what happened to an Air Force TSGT recently who was kicked out for posing in Playboy, even if the gay ban were removed and homosexuals were allowed to serve openly in the military, he would have been chaptered for some sort of honor violation for appearing in a pornographic video.
My question is - if a heterosexual male soldier was found to have appeared in a hetero porn video, would they prosecute it as vigorously as they do gay porn or a female soldier appearing in a porn video? I think not, but I'm just a little cynical about senior brass' willingness to use their moral reasoning skills.
