Interaction problems with Yahoo! Video

I have seen the beginning of Bill Scott's Yahoo! Video presentation several times today! The reason for this is that there is no way to know which interaction widgets are in-page interactions and which are cross-page interactions. Given that the presentation is about UI the problems on the page are all the more prominent. For example, "Share by email" is a cross-page interaction while "Save to" is in-page interaction (actually a pop-up window interaction) and yet they have the same visual design; the "+Add" is an in-page interaction even though it looks like a button which normally affords cross-page interaction; the rating stars are a cross-page interaction when generally this is an in-page interaction (especially when logged in).
