Chinn,
Thank you for your answer.
My problem is that after the commercial I see nothing. I waited for 20 minutes, and nothing hapend (I have fast internet, the commercial is loaded in 10 seconds).
Pressing the >-button plays the commercial again.
Is there anything I have to do to see the webcast?
Btw is it a US-only webcast? I live in Europe, so could that be the reason (region-protection)?
