Undefined index: duration

There is a notice that pops up when using the powerpress shortcode. Here is the shortcode I am using:

[powerpress channel=”channelname”]

The notice that is created upon use:

NOTICE: C:\wamp\www\domainname\wp-content\plugins\powerpress\powerpress-player.php:796 – Undefined index: duration

It does not affect functionality but should be addressed. The shortcode works well and does what we expect. We are using Blubrry PowerPress v7.0.3.
