I know that they have been cracking down on the down loader.
They are on the machine, because I can replay them with my internet disconnected.
Do you mean that you can go to YouTube, play a video, disconnect from the net and then hit play again?
I just tried it and that works for me too but I don't think there's a file. I think it's just in a memory buffer in your browser or Flash player.

I doubt if there's much to worry about. If the downloader is done well, YouTube shouldn't be able to tell the difference between that and playing a stream. If there's copyright material on YouTube then the owner tells YouTube about it and it gets removed. It's hardly the same crime as downloading a pirate movie via a peer to peer network.
Dunno 'bout Windows, but I do know on Linux the files are stored in /tmp.
You can just rename them before closing the browser/going to another page - after they've downloaded completely. Once you've renamed it, the player looses track of it and can't delete it. Move to my /home/<user>/Videos directory for future, offline viewing.
