@Heyou - I use a custom column called duration/Duration of Column type Date with format 'mm:ss' to do this. For me it's not worth having 'hh:mm:ss' because very few of my audio/video 'books' run for more than hour.
Addendum - I just discovered it doesn't sort as one might hope it would - I never tried before now. Can't imagine why I would want to sort on it.
