Vimeo Music box in "just featured"

OK guys and gals, you know on the right hand side of the music city theme (using Joomla 6.1) where it displays the vimeo video. I realize this function can be found under the modules section in the back end:

Module Description This Module allows you to create your own HTML Module using a WYSIWYG editor.

well I went to change the name and now no more video and I am unsure how to add another. I don't use vimeo anyway, but use YouTube.

So my question is can I just add a youtube mod in the right_top section?

This is my first attempt at Joomla so go easy:)

If you want to see the site its: www.MidSouthRocker.com but barely its been touched except some top level menus and links.

Maybe this helps you out! Paste your embed youtube or video code here and resize:

http://www.tools4noobs.com/online_tools/youtube_xhtml/

After that just paste the new code it into the xhtml module!
Hope this helps.
