Your really think were going to go through all that code? How about narrowing it down to say... line 214.

[Xtremer360]

Here's line 213-215

 

# Don't automatically add the player if the page is a feed, the player has already been added, or the user has the automatic player option disabled
	if ( is_feed() || $this->_playerAdded[$post->ID] || get_option('pod_player_location') == '' )
		return $content;

I would probably try...

 

	
if ( is_feed() || isset($this->_playerAdded[$post->ID]) || get_option('pod_player_location') == '' )
