The video shows fine in the article but my page is set up to display new articles/items in the sidebar and it is way to large.  You can see here: getyourgeekon.info/edu/index.php/item/122-classdojo  how can I fix this?

Either your search engine is crap or no one has had this problem which I doubt.  I have found no help here as of yet.  Anyone there? 

I saw this: 
8. Includes 3 templates: Classic, Framed and Responsive

I am not sure if this is what i need to do.  If it is I can't find on how to change it.  I use Joomla 2.5.6 

The videos looks just fine...
