Just checked foe a software update and lo and behold update 15.11.0 installled.
I then switched to BT sport and pressed record - It works !
Might now get the extra channels
Had to manually force the update & now recording BT Sport HD 1 & 2, whilst watching a terrestrial program.
Looks like maybe you could record 4 programs at once as long as 2 are internet channels.
Just tried & it's only 2 recordings at once but record 2 internet channels & watch a terrestrial so not too bad.
Is this only available to those with Infinity?
I have updated my box to the latest version but do not have channels listed in the 400s and upwards but cannot even record from BBC iPlayer.
Nowhere in this post does it mention Infinity being necessary
Bt only deliver the EXtra and BT Sports internet channels over infinity so to receive them you do need infinity and subscribe to the channels. When they first introduced the BT internet channels on Youview in August they could only be viewed as live transmissions. The latest software update (today) allows them to be recorded , paused etc.
The catchup players including BBC iplayer that exist on Youview cannot be recorded so you are only able to watch them for as long as the catchup provider makes them available. You can of course record the BBC programs when they are broadcast on the linear Freeview BBC tv channels.
