I have a Tivo Series2 and have always loved it. I have built a new home and the area I'm moving into does not have cable and will likely not get cable for at least the first year I'm there. I will be forced to subscribe to either DirectTV or DISH Network. Is there any way that a Series3 unit can be used to control either of these services? I was going to order an HD unit, but I've been reading that they're all gone now.

Can the SD unit display a picture on an HD TV that would appear presentable? What are my options with out being able to use Cable Service? I would be willing to sacrifice pure HD picture for Tivo controled season passes if that's what I should do. I have an HD LCD TV that shows a real tolerable picture out of my series2, would I be able to expect the same thing from a non-HD DirectTivo unit?
