Rob on "Websites video player no longer streaming youtube videos with wordpress 3.8"

I've just realised the videos linked through youtube are no longer playing on my embedded video player (http://www.flashxpert.net/products/video-players/video-player-iii/). Instead we just see the loading icon turning indefinitely. See - http://www.asworldsdivide.com

I've run a series of tests, including reloading the original VPIII deploy file in case my video was no longer valid, and found that the same errors occur. Meaning the problem has perhaps arrived through external changes... hence my proposing the WP update is responsible.

Can you think of a specific update that may have caused this? Is there a work around?

Below is the code the player uses:
