Swapping Sky box

[LeadFarmer]

My Sky box is faulty, it keeps pausing and jumping forwards.

I have a spare Sky box, so can I just swap them over and insert the viewing card into the new box? Will this preserve my recordings on the faulty box to watch later?

Thanks.

The recordings are on the hard disk in the box. If you change box you lose the recordings.

But I will be keeping the faulty box, so can I just swap the viewing card back into the faulty box when I want to watch the recordings?
