Video locker script?

Hey fellow blackhatters I wanted to know if anybody know of a good video locker? I'm not talking about the video share ones either. I'm looking for one I can use with CPA networks. I'm talking about one that stops the video after a couple of seconds of showing it.

So you are asking for script like the one on porn site, when you stop the video they show you ads.

Or you want it to stop your video and show ads/cpa?

If you do that 99% of your visitors will leave when they get locked.
