How to force 480p video quality for iframed Youtube videos?
Sample code:
<iframe width="560" height="315" src="http://www.youtube.com/embed/FqRgAs0SOpU" frameborder="0" allowfullscreen></iframe>
Append the following parameter to the Youtube-URL:
144p: &vq=tiny
240p: &vq=small
360p: &vq=medium
480p: &vq=large
720p: &vq=hd720
For instance:

becomes:
src="http://www.youtube.com/watch?v=oDOXeO9fAg4&vq=large"
