IOS 5.0.1: HTML5 Youtube embedding doesnt work anymore.

Hello, used a previous version of the player, to my knowledge we havent had any problems with the player. I updated the player to the latest version and now people are saying it doesn't show the video any more.

Cant verify if it worked or not as I haven't had chance to test with an Ipad until now.

heres my JW code

<div id="container">Loading the player ...</div>
<script type="text/javascript">
jwplayer("container").setup({
'file': "<?php $key="Youtube"; echo get_post_meta($post->ID, $key, true); ?>",
'image': '',
'skin': "<?php bloginfo( 'template_url' ); ?>/mediaplayer/skins/boc2/boc2.xml",
'stretching': "fill",
'height': 360,
'width': 640,
'modes': [
{type: 'flash', src: '<?php bloginfo( 'template_url' ); ?>/mediaplayer/player.swf'},
{type: 'html5'},
]
});
jwplayer().onPlay(function() { $('#slides_container').cycle('pause'); });

jwplayer().onPause(function() { $('#slides_container').cycle('pause'); });
jwplayer().onBuffer(function() { $('#slides_container').cycle('pause'); })
jwplayer().onIdle(function() { $('#slides_container').cycle('resume'); });
jwplayer().onComplete(function() { $('#slides_container').cycle('resume'); });
</script>

using Wordpress (latest version) so please ignore the php template stuff. the youtube address is stored in a page custom meta blob

the bottom half controls the housing slider app (this works in IOS still)

wondering if JW player supports the HTML5 embed code for youtube yet?
if not is there a way for me to maybe switch the flash code for the official youtube embed code? the API is a bit out of my depth.
http://britishorthodox.com is where the player is atm.

thanks for a brilliant program.
