Hi, I have check pages you mentioned. http://www.anapaolasa.com/15/ and http://www.anapaolasa.com/tramonto/ all works viewed from my end. http://www.anapaolasa.com/video/ here three video urls all have not parameter v=xxxxxxx.
another thing: the teddy theme original design is show audio and video content in post list page rather than in single post page, that is the point.
