If you scroll to the tips link, it tells you all about recordings and streaming to other boxes

The only issue I see, is if you have a V6 and a Tivo, for them to be able to "pair" to watch recordings across devices, you need to wire your old TiVo to the superhub via Ethernet or powerline :-(
"
With the V6 box you can start watching a show on TV downstairs, press pause, and pick up where you left off in another room, on another box.
First you’ll need to connect both your V6 box and your other TiVoŽ box to your Virgin Media Hub. For your V6 box you can do this via Ethernet, WiFi or Powerline. For a TiVoŽ box you can do this using Ethernet or Powerline."
