Picture and sound freezes at approx. five second intervals when watching recorded programmes on one box recorded on the other box.
Thanks for your post and welcome to our community.
I'm sorry that you're having trouble with the picture and sound freezing when watching recorded programmes. We'll do our best to get this fixed, don't worry.
Does this happen when watching live TV or On Demand programmes?
Does a reboot of the box help at all?
Let us know and we can help further.
