A method for providing event data from cross-referenced data memories of an on-vehicle event detection and reporting system includes cross-referencing event data stored in an event buffer with continuous video data stored in a continuous DVR memory. A request for additional data corresponding to a detected driving or vehicle event may be received by the on-vehicle system, where the request includes an event identifier corresponding to a detected driving or vehicle event. The requested additional data is identified in the DVR memory using the event identifier and based on said cross-referencing between the event data with the continuous video data stored in the DVR memory. The identified additional data is then transmitted from the DVR memory for display on a user computer.
