I never thought of it, but just download the "embed code" from any video, then put in the link, ... is that right?
That should work too.
In this instance, I am using Firebug, a browser debugger tool for the Firefox web browser. Awesome tool. Safari has a similar facility built-in.
It lets you inspect and modify HTML, copy, etc. I use it often to post stuff. You can edit the page and dump extraneous stuff before posting it.
To find and post this video with Firefox/Firebug:
Open the YouTube page and the Firebug console
Click on Inspect Element to inspect an element
Hover over the video, highlighting it, then click to select it
In the source code view, the < EMBED > code is selected and highlighted
Right-click on the source code, select Copy HTML from the popup menu, then paste it here at 4um
It took at least 50 times longer to type the description as it took me to lift their embed code. I spent maybe 15 seconds to open the video page at YouTube, invoke Firebug, Inspect, copy and paste. Another 5 seconds to make sure with Preview that it would play this way here at 4um.
