Just spoke to CS they have taken my details to call me when the release date is for Belfast. I asked her that I had a second box already, she confirmed that they will install the PVR and leave the second box where it is, the cost is £10 per month for the PVR/HD and £5 for the second box.(free installation), so really not costing anymore than I'm paying at the moment

.... at last some good news from NTL
