Yup; all but a select few that are available at the "showcase page".
LH give a coupla months for people to grab movies, etc, before they cleared everything out but, if you don't have something now, chances are it's been lost (movies wise, there's a chance if it was a well loved movie, it might have made it across to TMUnderground).
