How about the ability to create your own 'channel' on your BT vision based on On-demand (and maybe recorded) content.
I have a 5 year old and the menu for selecting new on-demand is tricky, especially if you want variety. I you like to be able to creat 'his' channel where I have preloaded maybe a postman pat, then a bob the builder, then a bit of playhouse disney. He can then go to the 'channel' and watch a (arranged by me) set of programmes without having to navigate the menu.
Call it 'his' channel, he selects it and the on-demand streams according to the playlist
