I've been able to watch live TV via the mobile BBC website for months on my X1. And to Andrew, you can watch live TV on your wired PC http://www.bbc.co.uk/bbcone/watchlive/
The Beeb hope to use the ethanet port to stream the iPlayer to the box (same for all Freesat boxes). Fingers crossed we will see this feature before the end of the year.
