OK, to embed a Youtube video the YOUTUBE TAG MUST BE CLEAN. It can't have any other info but the link to the video like this.http://www.youtube.com/watch?v=xc4B9PGnGtg
<--- RIGHT WAY
After you copy/past the Youtube link, highlight it, and click the Youtube button up top.
You will need to find the base link in its raw form without the words EMBED or FEATURE in the linkhttp://www.youtube.com/watch?v=aGpWurEQ ... ure=relmfu
<--- WRONG WAY
You will also want to put a link right above the video for people on smart phones like this.http://www.youtube.com/watch?v=dyzTXXvcSKk
