Read this: BT YouViewers can now record internet channels - PC Advisor

Summary: A software update for BT's Humax YouView box now allows it to record internet channels in the same way as regular aerial ones. This will be a phased roll-out managed by BT so some customers will get it today/tonight and the rest will get it in due course. Users can still record two channels at the same time, regardless of whether they are internet channels or broadcast channels. - pcadvisor.co.uk
