I have tested this on an iPad and PC/laptops with Chrome. The address to use is htpp://delimano.usp3.net as this is a redirect that can follow any changes we make.

This is a quick test to evaluate the video quality we can get from the YouTube presentations - it's not really good enough for a proper job, but it will show an idea of what is possible. Once we get video quality that can do justice to a TouchCast, we can go further.

Activating some of the "video apps" in this pause the main video and zoom it down to the bottom right corner - others allow the zoomed video to continue to play. It's up to the creator to choose. There is also a hotspot on one of the original "popup" graphics  - touch the PFOA graphic that appears at 46 seconds in.
