dvdnav_status_t dvdnav_relative_time_search	(	dvdnav_t *	this,
		int	relative_time
	)

Seeks the nearest VOBU to the relative_time within the cell relative_time is in seconds * 2.

If you want 5 seconds ahead relative time = +10. If relative_time is negative, then look backwards within the cell. max seek interval is 60seconds. for some reason dvdnav seems to return an error when seeking above 60 seconds on some dvds.
