The Vuze site states that this capability only works for Series 3 TiVos. I did get it to work for one of my Series 2 Tivo for a short time when Vuze had incorrectly discovered the TiVo as Series 3. The converstion (handled by Vuze) went quickly, and the transfer to the TiVo was faster than HMO between my TiVos (both wired). I love it. Now if they would only support Series 2!
