Aspects of an audio/visual architecture are disclosed. In one aspect, a system is disclosed where the system has a media manager object, an audio/visual program, and a player/recorder object so that when the program is selected, the media manager dynamically loads the player/recorder object for either playing or recording the program. For example, with respect to the media manager object, it can manage a collection of related program entities and any corresponding player/recorder components. Also, the media manager can allocate share source ports and shared sink ports in order to dynamically create virtual circuit paths for selected program entries.
