Really though? you had to pay to view the interview? Doesn't that seem sort of odd to you?
I think this is more of a firefox issue than anything else, because chrome (haven't tried IE yet) works just fine.
I click the link and it just starts playing. I don't have anything crazy installed, just windows, chrome, and vlc player (that and xvid codecs). Might just be a sign that firefox doesn't support it.
