So there is no way to add in video ads to the regular plugin? Or would it be a metter of getting the pro version in order to get help with that?

Most of the above codes are JavaScript, so I think it does not have to be added to any of the php files, but either to one of the files in fv-wordpress-flowplayer/flowplayer folder (possibly flowplayer.min.js) or to one of the files in fv-wordpress-flowplayer/js).

Unfortunately I don’t have any funds that I can spend at the moment, so I will try to figure it out by myself.

Thank you.
