BBC iPlayer crashing BT HomeHub?

I've just tried to watch 2 clips of events at the Bejing Olympic's through the Flash based version of BBC's iPlayer on my PowerBook. Each time I did I heard my BT HomeHub click to say it's restarting. The first time it did I just assumed it was just a random crash. The second time I thought something was definitely up as I've never had the HomeHub crash twice so quickly, it's been rock solid for the past 10 months. I can't believe a Flash based piece of software could actually crash my HomeHub but it does seem that way. I've watched BBC content via the BTVision box before (while it was free!) and not had a problem?
