A technique for determining cell starting times for DVD titles entails maintaining a snapshot in memory of starting times for the "most likely" to be played cells, and maintaining in memory a list of "hints" so that starting times for cells outside this most likely list can be quickly accessed. The "most likely" to be played cells are those of an active program chain. An active program chain is the program chain currently being played at any particular time. The hints list can be provided by a chapter array which contains starting times of only chapters (e.g., PTTs) of an active program chain (e.g., PGC). The snapshot in memory of starting times of most likely to be played cells can be provided by a cell array that contains cell starting times for only cells of the active PGC. The stored information is sufficient to determine current running time of a title. There is no need to store starting times for PTTs or cells of non-active program chains.
