A settop box system for capturing and controlling live and recorded audio and video content. The system records digital and analog data from video and audio content, such as in a home entertainment center. The system records data from the content as specified and the data may be sequenced into clips that can be searched and indexed. A user may create comparison programs that allow searches of either pre-recorded or incoming content to be performed. In addition, the program allows editing of recorded programs, such as filtering of audio content or overlaying a video program with a different audio background. Multiple audio and video feeds may be handled simultaneously and the program's functions may be executed without viewing of the content being manipulated. The recorded content may also be indexed and even clips of the content may be indexed.
