The answer is what you don't want to hear.

You can make it difficult for the average user to download them (by blocking the right click save option using javascript, using flash for the video, etc), but there is not way to guarantee that no one can download it.

By putting the full video on a website, you are permitting a user's browser to download it.

The recording industry has spent millions of dollars to try to do what you want to do - to no avail.

There plenty of browser plugins to capture streaming content.

And I will also back up what both of the others have said... because I've found ways to get around those restrictions myself, and its not that hard.
