Searching the web for applications to grab embedded video (you-tube and lots else) I find there is a lot of stuff for Windows and discussion of techniques used but the search for Mac equivalents is frustratingly meagre. I have found only the shareware YouTube Video Grabber 2.0 which needs Leopard whereas I have only Tiger 4.11. Am I missing other important applics? And does one need extra software to locate the URL to download?
