A system includes a cache, coupled to a receiver, to store received content and advertisements. An interface in the receiver detects the occurrence of an advantageous condition during the play of content retrieved from the cache. The receiver locates one or more advertisements in the cache, and enables the display of a user interface in place of the content so long as the advantageous condition is detected. The user interface includes selectable indicia of the located advertisements and an indicia of the content. The interface is adapted to locate one or more advertisements using markers that are inserted into the content by the interface, and pointers to the one or more advertisements associated with the markers, the pointers having a stored association to the markers.
