If you're in the loop, you can use PHP code to get the podcast data in an associative array. Function is called powerpress_get_enclosure_data. I would code something like this...
if( function_exists('powerpress_get_enclosure_data') )
$EpisodeData = powerpress_get_enclosure_data($post->ID);
if( $EpisodeData )
$url = $EpisodeData['url'];
// what you need to do here...
This is what you are looking for correct?
The $EpisodeData has the following fields:
id - post id
feed - feed slug (podcast default, but if podcast channels is on then this is different)
url - url to media file
duration - time in seconds of media
size - size in bites of media file
type - content type (e.g. mp3 = audio/mpeg)
width - video player width
height - video player height
(there is more if you enable other options in PowerPress, but you get the idea)
