Youtube automatic posts the video does not play on iphone!

I am so frustrated! I love your plugin, but I have another plugin that automates thumbnails and none of the automated posts thumbnails showed up because of the custom fields and short url. The developer sent me a line of code to recognize automatic posts thumbs and I was so relieved to be able to add your plugin to the work flow! Then today I was cleaning up some last details on the mobile theme and noticed that all the posts brought in by your plugin do not play on the iphone. The player shows and looks good but when you click the play button you get the circle with a line through it. Any ideas??
