Hello,
I'll wrap up setting up the current site and the clone it to test the development version.
Yesterday evening I found a workaround as I am not using Powepress to play videos in Wordpress as I need to use JW Player.
In short go to the Powerpress video settings
Configure HTML5 Video Player page and link a new
Default Poster Image.
In my case it was a 32x32@72 png image
Then set the player width to 32 and height to 32.
Untick
Include play icon over poster image when applicable And you will now have a nice PDF image in place of the video window.
here are some screenshots
