Have you tested on a device?
I had not since there was no point in continuing like that, but I have now.
It lines up correctly, but renders very slow on my iPhone 4. I mean maybe a 1cm block per second rendering. Then it moves very slow too.
I have a top of the line new MacBook Pro Retina so there should be no performance issue with the computer side.
The app is just a test app with one screen of bubbles moving up the page. It's a tutorial I am working through. SO the problem seems to be mostly with testing the movie in the ADL
On-device testing is a must. I develop from Windows and I can't see any video in a StageWebView or from the StageVideo class haha. I'm very used to testing being limited. You'll find that more and more as you go.
