Storing the password on a script is not recommended irrespective of which ever technique you may be using. One work around would be to store a random file on a flash drive and use it's hash (or value from it) as the password. So that you can remove it when not in use.

Some good answers here. But what might make this all simpler is to just say that the encryption is linked to the current account that you are logged into when you encrypted. Try creating a new account on that machine. (even an admin account) Log into the new account and now look at the file (in place, without moving it off the system). You can't read it now ...

It would be better to "stand on the shoulders of giants" and use existing DRM solutions. Windows Media Rights Management and PlayReady are good solutions. The latter supports HDCP and are used by mainstream premium content ...

This is a problem of trying to protect what you want to provide. It's impossible to do, but you can make it difficult. Probably the best approach would be to encrypt the files. But at the end, you give all the data for a person to run on a computer they have full access to. Since it will play the video at some times, it means the keys will be available in ...

As you state in the question, doing this in a foolproof way is technically impossible. For the video to be displayed on the screen it must somehow reside somewhere in the RAM on the computer, be transfered to the monitor and then displayed there. From all these points the video could be extracted. Possible ways include: Copied from RAM. Recorded with ...
