Do_Shortcode with embed code not working

I’m trying to use Custom Field types to embed Youtube videos in a more organized fashion and using the Do_Shortcode() would seem to work perfectly, however this:

<?php echo do_shortcode('[embed]http://www.youtube.com/watch?v=K0M09Ws8vpc&feature=player_embedded[/embed]'); ?>

Does not seem to work, however in the same single.php file this does work perfectly:

<?php echo do_shortcode(‘[gallery link="file" size="thumbnail" icontag="div"]‘); ?>

I put them one after another to test them out, any ideas why the [embed] shortcode doesn’t get parsed (it just shows nothing)

If I do the embed shortcode directly into the post it works perfectly.

Thanks,

Jordan
