are you using any code that you didn't write?
We are just using the Flash movie control and that is it.
is your answer, no you're using noone else's code except the code in native pre-compiled flash components? are your f4v files all local? did you create all the f4v files so you're sure none of them is causing the link?
Yes we are using all our own code except for adobe flash components.
I created the f4v myself with adobe media encoder.
Yes all the f4v files are local.
then that url is injected from somewhere else like your server. if your information is correct, it's not from flash.
