Adding video to posts

When you see a YouTube video you wish to use, place your arrow anywhere on the video while it is playing or paused and then right click your mouse.  That will bring up a menu where you will left click on "Copy embed HTML". Open up note pad and then use the Control key plus the V key simultaneously to paste the code into notepad (or any other text application) and you will get something like this (without the highliting) :

<object style="height: 344px; width: 425px"><param name="movie" value="http://www.youtube.com/v/64jwukb9IhM"><param name="allowFullScreen" value="true"><param name="allowScriptAccess" value="always"><embed src="http://www.youtube.com/v/64jwukb9IhM" type="application/x-shockwave-flash" allowfullscreen="true" allowScriptAccess="always" width="425" height="344"></object>

You will then use the parts I highlited to fill in the blanks in the box that comes up when you click on the Insert/Edit flash command icon in FCK editor mode (the round button just to the right of the square icon for inserting images).

And there you have it - at least for YouTube videos.  Videos other than YouTube ones can be a bit trickier.
