I have an embedded object in my webpage which will play a DVD movie right in
the page (provided you have a disc in teh dvdrom drive).  One of the
javascript methods attached to this object returns the current time.  OK, on
to the php/mysql part.  I have a mysql database which has a table to catalog
camera shots digramed like so:
|*shot_num    |
|  start_time    |
|  end_time     |
|__________|  * = primary key

During play, I have a javascript function which continuously gets teh
current time and puts it in an input field called cur_time (clever huh?).
So my question is... what is the best way to have a second field called
shot_num which is continuously changing?  It can't be good to query the
database continuously, even if it is a small query, can it?  What is a good
stratagy to work with here?  I'm still a bit of a novice with php/mysql, so
be gentle.
