where flash video stores flv file path

Hi

i select from menu insert->media->flash video and then select the flv file and click ok and i try to search for my file to change it to dynamic criteria like <?php echo $row_rsfnames['fname']; ?> to get flv files from a database
How to do that?
if this player doesn't support this feature i need DW extension that can do this to get flv files from a database.
thanks in advance.
