language key _SYS_MEDIA_PROCESSING

I am looking for the code that displays this key.

I have the key in my language file,  but the key is displayed, not what the key is set to.

When a video is still being processed, instead of the video, it shows _SYS_MEDIA_PROCESSING

In my language file I have '_SYS_MEDIA_PROCESSING' => 'This video is still being processed',

Thanks!

Is that the exact case of the key? All caps?

The only key i have that comes close is _sys_media_processing  All lower case with the text File not processed yet

It is used in the file modules\boonex\html5av\classes\BxH5avModule.php

Can't see the forest because all the stupid trees are in the way!  LOL

Thanks!
