smart youtube not working on iPhone

I am having similar issues. My iPad 2 doesn’t consistently play the videos. Upon page load I can see the still shot, but then I click play and the area goes black while it loads. Then I can hear the sound, but no video.

I’ve played around with disabling the iframe as well and it “seems” to fix the problem for now. But I’m not convinced… because when I first installed the plugin using default settings (iframe enabled) it worked just fine on the iPad 2.
