The Simple Facebook Connect plugin is modifying the content after PowerPress adds the player and links.
To get PowerPress to add it's player after the Simple Facebook Connect plugin, add the following define to your wp-config.php, near the top of the file.
define('POWERPRESS_CONTENT_ACTION_PRIORITY', 40 );
The 40 here is important. PowerPress default priority is 10, and the Simple Facebook Connect plugin is using a priority of 30. So by setting a higher priority number, it means that PowerPress will be prioritized later int he priority order. (the priority of items starts at 0
