Downloading Streaming Quicktime Clips?

Hi, I am a first timer in this board.
I have a question. There's a certain websites(don't ask where...but no it's a legit one. ) with streaming Quicktime clips that doesn't allow members to download the stuff.

Right clicking the screen does not work. I use Netscape and what I did was to right-click on the clip page, go to Page Info, tap into Media tab and download the clip by clicking on save as button. It works. The problem is, it is very cumbersome!!!

Do I need Quicktime Pro or something like that? Combing through the cache directory doesn't help because the temp files for the clips are not that stable. (They change sizes constantly even to the point ot 0kb...) What should I do?
