Systems and methods for providing enhanced navigation of stored digital video content based upon a content-based index. Includes generation and storage of an index, as well as navigation based on the segments defined by the index. An example system is embodied in a digital video recorder that generates an index for locating commercial groups interleaved with program content in a video presentation recorded from a television broadcast. The commercial groups may be viewed without the intervening program content or otherwise navigated based upon information in the index and one or navigation functions. Example user interfaces and several navigation functions are also provided.
