I am thinking about upgrading to V6 box and moving my existing Tivo upstairs to replace V+ box.
What I am keen to find out is will I be able to stream the recordings on my existing Tivo to my new V6 box downstairs. I have the network cable infrastucture there already if that helps.
Any info would be greatly appreciated
Yep, if you're keeping your old TiVo as an existing box you will be able to stream from it to the V6 as long as the TiVo is connected to your home network with an Ethernet cable (and it sounds like you're all geared up to do that).
