I’m already a Virgin media customer using the new TiVo V6 as part of my package deal. What I would like to know is, can I actually BUY another TiVo V6 outright without it being added to my monthly package? And, how much would it cost for a Virgin engineer to install it for me in another bedroom?
No, not legally. Virgin Media do not sell their STBs and they remain the property of Virgin Media. If you were to buy an STB off someone then you'd end up with something you cannot use to access anything via Virgin's cable network. The reasoning being that Virgin haven't activated that device for use in association with your account at that address and will not activate it for you. You'd also technically be breaking the law by accepting stolen goods.
The only way to add additional boxes is if asking Virgin for them and having them added to your account.
