I haven't bothered with the red button, saved my money on Sky+ and Tivo
The BBC red button just seems to cover BBC3 which is on Freeview channel 7 if that helps.
BBC1
BBC2
BBC3
are showing different sports.
Try the link. The current match seems to be shown live, so hopefully the later matches will be.
Try msnbc or msn.com and google Olympics
My TV doesn't have the red button feature, but I wanted to watch the USA v NZ game in a couple of hours, is it possible to watch it on my tablet online? Thanks.
