Ive upgraded today from V6 to 360. I have four boxes at home, but told I can only have 3 boxes on 360, one main and 2 x mini. I can’t have any other boxes on the account, not an extra V6 or an older TiVo. So I have one TV now without a set top box and no TV. When will I be able to get a fourth box please? Do you know? Thanks.
