That video on Office Touch on this site plays fine for me; YouTube videos play fine too. However, videos on Facebook don't work and just freeze and sometimes freeze the whole browser. Also many sites that use Flash, including those for video don't work, telling me I need to upgrade the Flash player, which I don't think is possible to do with this browser. Also enabling experimental web platform features (Spartan engine) doesn't make any difference on the videos or on Flash.
