The DreamWorks SKG troika of Jeffrey Katzenberg, Steven Spielberg and David Geffen might well be nearing the end of a lengthy search for an executive to head its TV unit.

DreamWorks SKG, which has already signed “Family Ties” creator Gary David Goldberg and is aggressively pursuing top sitcom writer-creators as their contracts expire, originally hoped for Warner Bros. TV topper Leslie Moonves, who already has what many consider to be the best job in TV.

Sources said the trio is now in serious negotiations with Jamie McDermott, currently a senior vice president of comedy development at NBC. Perhaps better known by her maiden name of Tarses, she’s the daughter of “The Days and Nights of Molly Dodd” creator Jay Tarses. She worked with her dad when he created the short-lived NBC series “Black Tie Affair,” a testy working relationship that was said to be the inspiration for NBC’s recently canceled sitcom “Madman of the People.”

McDermott, who married Fox exec Dan McDermott, denied she’s negotiating to leave NBC: “It’s not true. There are no talks. I’m here. For now. I’ve got two years left on my contract.” Denials aside, sources said she’ll likely make the move right after pilot season is over.

There also have been reports that DreamWorks is in talks with Bob Jacquemin, the former distribution head of Buena Vista.
