Go to the Widget Setup page and create a new widget. Once created, click the User Widget Content tab and select
the widget you just created.
In the text editor, click the Source Code
button and paste the following text into the resulting popup box.
<iframe src="HTTP://YOURURI?rel=0" width="420" height="315" frameborder="0"></iframe>
Now, replace HTTP://YOURURI?
with the address of the web page that contains the video you wish to embed. e.g. http://www.youtube.com/watch?v=9Tap1_t0vjc.
Note that you can play around with the values for
the video's width and height - the numbers are measured in pixels.
Click OK to close the popup, then click the Save
button to commit your changes to the database.
