My WPMU DEV Video Tutorials not playing in Pro Site clients websites

I have set up Multisite – subdomain with Pro Sites. So far all is working great. I installed the Video Tutorials Plugin and in the subdomain websites I now have a Top Level menu item saying Video Tutorials. When I click on it I get the complete menu of videos. When I click on any title it “loads” the video at the top and when I mouse over the play button changes but I can not get it to play when I click on it.

I read in another thread that in Domain Mapping (which I use) to change the Admin Mapping to original domain which I have done.

On the DEV Video Settings it confirms my domain is successfully registered.

Need help getting the videos to play!

Thanks
