[ogg-dev] fishead granule rates

[ogg.k.ogg.k at googlemail.com]

Hi,

What are the two granule rates in a fishead packet supposed to be for ?
Since each of the streams has a corresponding fisbone packet with its own
granulerate in it, and they can be all different, wha does the presentationtime
num/den means ? Also for hte basetime num/den, since the UTC time which
is also present in fishead seems to be a textual representation rather than a
linear count ?

Thanks
