The first frame of the stream (if it hasn't been trimmed) is a keyframe. It is displayed between time = 0 and time = 1 * frame_rate. The granulepos for that frame is based on the count of frames after it's been shown, which is 1, not zero. The only Ogg pages in a theora stream with a 0 granulepos should be the headers. -r
