A segment of audio/visual (A/V) content is extracted from the overall DVD content of a DVD program or disk. A DVD player with A/V segment extraction functionality receives commands from a user that identify start and stop points in the DVD content for the desired A/V segment and that specify each of the available DVD options or features which may be included in the extracted A/V segment. Relevant blocks of data within the DVD data structure of the DVD content are identified and new DVD-standard information for assembling a new complete DVD data structure containing only the extracted A/V segment and the available DVD options and features and additional non-DVD-standard information that can be played back on a conventional DVD player are added. The complete DVD data structure is assembled and either stored locally or sent to a remote destination device for remote playback, re-editing or other use.
