### Description of your *issue*, suggested solution and other information

I've been trying to decipher how to download videos from paid subscription channels on freshlive.tv and have noticed that they are handled slightly differently to free content. The AES-128 key seems to be loaded programmatically as evidenced by the example below. My javascript is severely lacking so I've had difficulty working this one out. I have credentials which may be needed for testing.
