It has worked pretty good. With IE9 things are getting more complicated. I want to exclude IE9 which is capable of HTML 5 from the if-area but keep the fallback for visitors with Windows XP, i.e. IE < = 8. My PHP is poor. Can anyone help me?
Okay, I should have mentioned that the simplest way doesn’t work out. There will remain two video-elements in the DOM then. The other one cannot be removed so easily. There will be no video neither in IE8 nor IE9 then.
