chess.com videos never load with Cloudfront rule enabled

http://www.chess.com/video/player/evaluation-and-planning---part-1

This is an example of a chess.com video loaded through Adobe Flash. If the Cloudfront rule is enabled (as of version 2014-4-25) then the video display will show permanently as loading (in the form of a spinning circle). Disabling the Cloudfront rule causes the video to load immediately.
