As a wild guess you probably referring to Riki Rachtman. His name is spelled a dozen different ways. He used to do a TV Show on MTV2 called The Headbangers Ball. It dealt with heavy metal rock. He was on KLSX radio in Los Angeles before he punched out a fellow DJ and was fired. He was the boyfriend of Janine Lindemuller, Vivid contract gal. She did mostly g/g for Vivid and she was 1/2 of Blondage.
I don't know if he ever did a porn themed show but he would be a natural for it.
