Tivo and SDV

[Reckoner]

Well I picked up a Tivo HD this past weekend, and all is good so far. I'm still in the trial period, and I'm deciding on what plan to choose. The 3 year seem likes the best deal, but there's always the threat of SDV expansion in the near future, especially since I'm near the Boston area. I know Tivo's working with the Cable Industry on this, but I'm not getting my hopes up. What's your guys take on this?
