Actually the Javascript call is unrelated and doesn’t affect the playability.
The problem appears to be the number of video embeds you have on the page. Because of the amount of content that each video player loads when there are eight video players to load simultaneously, it is causing the Chrome Browser to not load the page properly.
Why the lock up happens in Chrome, and not the other browsers is beyond me. You might try using this jQuery appear (https://code.google.com/p/jquery-appear/) plugin to only load the videos which are on the screen, that should fix the problem.
YouTube, and other video services have similar issues, when more video embeds are loaded simultaneously it creates a bottleneck, and Chrome just happens to handle it the worst.
