Dont be expecting any new channels soon, from whati know Living HD is exclusive to Virgin, although sky are still in talks i do know that Sky News HD will be here next year but apart from that nothing. Id love to see 5HD now that would be nice.
When a new channel launches, they tend to feature the big-name shows from that channel on Anytime. I knew nothing about DisneyHD 'til I saw 'Cars' while flicking through Anytime. Same thing happened when FXHD launched.
