While I’ve seen some things that claim that they can do all of that, block everything and can’t be bypassed… they call can. The longest it’s taken me was just under 4 minutes – and I am not even remotely close to a hacker!

The only option that I can think of that would work is to set up all of the videos to be hosted on your own site, then set up access only through a PHP fie that checkes that the user is properly authorised before the video can be loaded. There’s a lot more to it than just that, but it’s possible if you do want to be paranoid about it. ??
