First things first, it says "you are using Midori 0.4" but the current Midori version is 0.5.10. You are
twenty versions behind according to
http://midori-browser.org/changelog/ ... why are you expecting such an old version to have compatibility with modern websites??
Second, I notice the Midori FAQ has a lot of tips about video/multimedia. Which of these suggestions (if any) from the FAQ have you tried so far?
