If you're using Firefox, go to "Tools", "Page Info", then click on "Media". There should be a .fla file there. Right click on the .fla file, click "copy" then open a new tab/window and paste the URL there. Next go to "File" then "Save As..." and download the file. Make sure the file extension is .fla when you save.
 
well i am not sure but i think it is because its what they call a 'progressive' video not 'streamed' so it does not buffer up like youtube videos thus not allowing you to save them.

some one correct me if i am wrong
 
Chances are you won't be able to save the original file since it's actually streamed (and not cached and played back like Youtube does), and there are no good rtmp clients for osx afaik.

Edit:

Correct, except the other way around; progressive reads the file into the browser cache and streamed receives it from the server bit by bit.

Alternatively you could use a screen recording app like iShowU.
 
Have you tried Zamzar (zamzar.com)? I prefer vixy.net for ripping youtube videos but vixy doesn't seem to work on your Yahoo link.
