Make sure you’re browser is up to date. Check your internet connection speed. You can do so using speedtest.net. Also, at times you may find videos take a bit longer to load depending on your connection speed and many other factors. A videos are severed from the Cloud and should load well for most people. Video are played via the modern HTML5 video player. No Flash Player needed, though Flash fallback is running just in case.
Videos play in Safari, Goggle Chrome and Internet Explorer. Firefox uses a different video codec and does not work at this time. I am looking into solutions.
If you are still having issues, please Contact Me with information on what browser, operating system and the things you have done so far to try and view the videos.
