Realizing it is not possible to fully prevent someone from downloading a streaming video, what is the most secure way I can keep the videos on my user-authenticated site from being downloaded and/or distributed?
Some technologies that come to mind:
The content is very costly to make and I can't afford to make it if it gets ripped off so it's necessary to at least slow the pirating as much as possible. I'm open to any DRM / streaming / authentication technology, free or paid, as long as it works.
ABSOLUTELY NOTHING!
Nothing is stopping people from getting a program like Expression Screen Encoder and recording the screen.
Sorry
In the meantime i would probably go with Silverlight + PlayReady
