Indeed. Frustrates the HELL out of me even more because all their videos are available in web-friendly MP4 for the mobile services and you can get to them if you spoof the user agent. I wish they would just let me toggle a "beta" feature or something.
Yes I was aware of the iPlayer HTML5 opt-in which is what I was hoping to see for the rest of the site. Given that they have all the content in HTML5-friendly video anyway it shouldn't be all that painful.
