It ain't Jeff, or any other mod. Youtube is not allowing embedding at the request of the person who uploaded the video to Youtube
On the bottom right, there is a little embeded upward pointing arrow. Click on it, and a little box will rise up. Copy the address in the "URL" box by clicking once with the left mouse button, once with the right, then select "Copy".
Paste that address in your address bar and watch the video. Good stuff.
or . . . one could go to "sothink.com" and download their software for "downloading" these videos (its' free) and save the relatively small file on their computer and then get the free "flv player" and watch it even offline.
They also make a product (NOT free) which will convert these items to "AVI" files.
