OK, I've just checked out the ad settings and it appears that anyone from the outside the UK or using AOL/Proxy will be getting TiVo ads or some which include a talking smile banner
I'm removing the network now, as I've told them to show no flast/sound/annoying banners and only PC related ones.
Sorry about that guys
I'm trying a Bulldog broadband banner for the UK (going to give a try to different ISPs and see which one works). I'll disable ads for outside the UK until I can get a "fixed" banner that I can approve myself
