Yes. The Video Recordings Act requires that all elements present on a DVD (or video) must be classified. This includes not only the main feature but also any 'extras', such as trailers, deleted scenes and other special features. If a film has been classified for video release, then there is no need for the film itself to be resubmitted for DVD classification, provided that the DVD version is identical to that released on video. However, if the version of the film intended for DVD differs in any way (eg a widescreen version), then it must be resubmitted.
