The sentencing caps a sometimes bizarre, five-year, three-trial legal saga. A 2008 trial was halted after the Los Angeles Times reported Alex Kozinski, chief judge of the 9th US Circuit Court of Appeals, had sexually explicit material on a personal website.
Kozinski, who presided over the trial, recused himself and was admonished by a special committee of his colleagues.
Isaacs was indicted as part of an effort by a Bush administration task force to crack down on smut in the United States.
At issue at the trial was whether the videos sold by Isaacs were obscene. The test hinged on a 1973 US Supreme Court ruling that held that a work is not legally obscene if it has "literary, artistic, political or scientific value."
Jurors also were asked to decide whether the videos violated standards of what is acceptable to the community at large.
Isaacs defended himself as a champion of free speech, but he found very little support in the more mainstream porn community.
