Same has started happening to our YouView over the past couple of days. It was fine, our Infinity connection seems fine but all the internet channels stutter badly now.
We've rebooted the YouView box and Homehub router, disconnected all other devices (which are functioning correctly) but to no avail.
Basically BT TV is a rip off, they've got a real cheek to even be charging for this junk. We've had one issue after another. My long held view that BT are scum has been completely confirmed.
I have noticed this tonight - is it a recognised fault? I have only experienced it since the last S/W update
