MKDR25,
Same as you, I have 2 V+ boxes already. I've arranged to keep both of them and have one moved to another room AND have a Tivo as well. A few days after I arranged this we got a call to say that I would not have to pay the extra £6.50 multiroom cost for keeping the 'extra' V+ box
I'm assuming this is what DF mean't when he said existing multi-room subscribers would get something a while after arranging/getting installed?
