Hey Brad,
On the iPad in Safari HTML5 nor Quicktime worked.
On this one computer here Safari: QT doesn’t work, HTML5 does work, Firefox QT asks for plugin, but then can’t find one to install and HTML5 doesn’t work, Chrome HTML5 works but it is stuttery.
On another computer Safari: QT does work, HTML5 does work, Firefox QT works but HTML5 doesn’t, Chrome HTML5 works, QT works after it asks to allow plugin to run.
