Specific Youtube Clips don't embed with Youtube Chromeless

I'm having some issues with Youtube clip embedding using the chromeless jQuery plugin. http://www.viget.com/inspire/youtube-chromeless-video-jquery-plugin/

Most of the videos I embed work fine, but there is a specific 2 videos which refuse to embed.

I have setup a test page which has a working video and the 2 broken videos, on the same page. (Link no longer valid)

The videos which do not work are .mov files before being uploaded and both came from the same producer.

I assume that this is an encoding related bug, but thats just my guess. Anyone have开发者_C百科 any other ideas?
