I am trying to integrate some advert code into the JWplayer but need to find the source file for the following lines of text, taken from the video page.

so.addVariable("linktarget","_blank");
so.addVariable("width","640");
so.addVariable("height","390");
so.addVariable("displayheight","370");
so.addVariable("overstretch", "true");
so.addVariable("autostart", "0");
so.addVariable("bufferlength", "5");
so.write('vshare_player');

I need to add some more lines to those above but do not know which file this code is located in...Anyone?
