How best to progress? I have: Sky+HD in room 1 SD Sky box in Room 2 Room 2 only has one cable feed. If I purchase a "new" Sky+HD box from EBAY, can I simply swap out old Multiroom SD box for new Sky+HD? Assuming I set it up for single signal feed - can I then do "self set up" - or is it a call to SKY to pair m/r card to new box? Will there be issues with pairing under those circumstances? SKY website doesn't seem to offer a clear upgrade path for my scenario so I am thinking the above method is easiest - unless anyone can suggest alternatives? Thanks.
