[Plugin: MediaElement.js – HTML5 Video & Audio Player] Can't centre player

Having trouble getting the player to centre in the post.

Tried <p> and <div> centers but neither work, do I have to edit the plugin itself to get this happening?

You can see what I mean here

The player is surrounded by <p style=”text-align: center;”> and still not centred.

Also, I can’t figure out how to get the songs to play on iOS devices. All I get is ‘Cannot play audio file’ where the player should be.
