admin/main.php

Hi, I'd like to alter the flash player display size to suit 16:9 - in the admin section, main.php

main.php is Zend encrypted. Does anyone know the tweak that will provide a solution or the location of the player script used on the admin/main.php page?

The aim is to change the player to:
$player_wdith = 470;
$player_height = 285;

Thanks
