For us to get this, 2 things must happen. The first you have already mentioned, the TiVO has to support it. At the moment the answer to that is no. Not even the US version does. Secondly, BT have to agree to wholesale the 4K version to third parties. If its anything like the situation with Sky 3D, you know what the answer will be.
