I have 2 x V6 boxes and a TiVO and have been booked for an engineer install for the upgrade. Is this correct as I thought it should be a case of updating the existing V6 boxes and swapping out the TiVO? Is it an engineer install as I have 2 x V6. With an engineer install I presume they will be replacing one of the V6 and the TiVO with mini boxes but with a home install I would have the advantage of keeping 2 boxes with recording capability,
