We have a drupal website, and using Colorbox to present our popup images and video. We have our product demo videos loaded onto YouTube that were created in HD. I need to force the YouTube video to play in 720 HD in the Colorbox popup window. Currently it is defaulting to 360 and you have to manually select a higher resolution. I have found all kinds of ways to force HD playback, but for other iframes and nothing that works in our Colorbox code.

Here is the code I have:

<p><a href="http://www.youtube.com/embed/FrLDc2HWALo?rel=0&amp;width=853&amp;height=480&amp;iframe=true" class="colorbox-load"><img src="I've removed the location of the image for company security issues" alt="VirtualViewer HTML5 Product Spotlight Video" width="677" height="393" /></a></p>

Please help, I would be ever so grateful.
