My company is relocating me to another state. My family will be in one location / state and I will be in an apartment in the other location / state. I will be there temporally, for four years. I plan to purchase my fourth Tivo; I have two series 2 and one series 1.

My questions are, I would like to be able to transfer programs from one state to the other, using the series 2 Tivos’ (both are on my home network) and one, I plan to purchase from Weaknees. Will this work? Should I get a series 2 or series 3? If I decide to go high definition, will I be able to transfer standard definition from one location to the other?
Thanks for your help.
Dick
