Like many others I always had issues with Flash.. Mostly heated up my system and had crashed on my system often. So I have decided to put all my videos on Fryetech in HTML5. Lucky for us Youtube is supporting HTML5. I believe its still in beta however I like it much more then Flash.
Youtube offers a little bit of code that will automatically switch back to flash on systems that don’t have HTML5 yet. (Code on bottom)
As of this time the only web browsers that support HTML5 that I know about are
Latest Google Chrome
Latest Safari
Here is the code in case you would like to post it on your site.
