The video starts with a blurry, low resolution quality, then stops, then starts up from the beginning again with a better quality.
Here is a screen capture of what it does on the page: http://content.bitsontherun.com/previews/VJWey8Ia-kL6K5MhT
Here is the actual video: http://content.bitsontherun.com/previews/LIWKZupr-kL6K5MhT
I output it again at a lower data rate and it still stops/starts: http://content.bitsontherun.com/previews/Ii68AWzJ-kL6K5MhT
Help!
By the way, I just tested on an iPad it plays perfectly without the stop/start blurry first frames...
