For some reason YouTube videos in my website do not get the fullscreen button, even if I added the parameter allowFullScreen set to true both in the object and embed tag.Here's an example page: http://www.indievault.it/2011/11/09/indie-vault-alla-games-week-2011-online-la-video-gallery/Just take a quick look at the source. The allowFullScreen param is there, but the button won't show. Here's an excerpt from the code in that page:<object width=540 height=325><param name=movie value=http://www.youtube.com/v/dvYQhJwwkgA></param><param name=allowFullScreen value=true></param><param name=allowscriptaccess value=always></param><embed src=http://www.youtube.com/v/dvYQhJwwkgA type=application/x-shockwave-flash allowscriptaccess=always allowfullscreen=true width=540 height=325></embed </object>
