After upgrade to JWPlayer 6, some streaming issues

Most of our videos work as expected after we upgraded to JWPlayer 6, but some won't stream properly. For instance, this one won't play until the whole video has downloaded:

Same with this one:
http://science.kqed.org/quest/video/better-bees-super-bee-and-wild-bee/

But this one works as expected, as do many others:

Could there be a difference in how the videos were created that would account for the different behaviors? The code is the same everywhere.

Hi, I’d suggest running the problem files through a video re-encode. It’s possible that the MOOV atom might not be located in the proper place. If you’re using Handbrake, I’d suggest making sure that the “optimized for web” checkbox is clicked.

Also, it’s probably a good practice to have this configured as MP4 for maximum device compatibility. I’ve noticed that these are M4V, which might not play nicely with all HTML5 devices.
