So I'm not a huge Olympics person, in fact I haven't actively watched any however I must congratulate the BBC on its Live streams.
The live player is really very impressive. Hitting the 'Extras' menu gives you so much information, especially during an event.
* Score boards
* news tickets
* rewind to any point
* Swap to any stream
So yeh, well done BBC. Please feel free to keep these features for all your iPlayer players.
