i am not sire what browser u r using. but usually you need to use flash player and flash extensions
.try using google chrome. http://www.google.com/chrome/eula.html
choose .deb. thats for ubuntu

mozilla might need an extension,it will tell you automatically when u r gonna play the videos. click on it, but please choose .deb package. not .bin
