YouTube viewer uses outdated embedding
The current YouTube viewer is tiny, and lacking the controls to switch to fullscreen mode or change the quality. It also doesn't make use of YouTube's new Widescreen feature.
YouTube has made an updated viewer, accessed through an iframe, which has a lot more possibilities, including a specific button to view the video on the YouTube site, which re-enables the use of clicking the video to pause it.
The new code is:
<iframe title="YouTube video player" class="youtube-player" type="text/html" width="635" height="382" src="http://www.youtube.com/embed/uY3d9-B6ikk
?rel=0" frameborder="0" allowFullScreen></iframe>
