I've installed the jce 1.5 and mediabox make it possible for the admin to place the expensive videos by uploading the swf files or by browsing the url in the youtube
I've enabled the mediabox wordpress plugin
but I'm not sure where's the expensive button is suppose to look in JCE.
thanks ahead of time
after looking for the internet
I discovered SWFContent Professional &lifier SWFContent Professional Module
this solved my problem :)
