Web Authorisation

In the Web Authorization window I have entered my login and password for a couple of popular streaming providers. Every program I select plays perfectly in the streaming website window in my browser, but nothing is triggering AntDM to show a video box or button. I've tried copying and pasting the URL shown in the browser but AntDM just downloads a small HTML file. Drag and Drop doesn't work. What is the secret to get the program to download through AntDM?

The Web Authorization (Apache authorization) should work exclusively for sites using classic authorization (for example rsload.net).
It will not work for video hosting, which use authorization as an element of protecting your content.
