Just wondering if the HD Tivo is worth it? I don't mean the money aspect. But with Directv severing its relationship with Tivo I'm concerned that I could shell out big bucks for it only to lose all functionality of it, say within a year when Directv comes out with their own HD DVR. I've been reading on this board that there is a good chance that DirecTV will upgrade HD receiver users for free or a small fee when MPEG 4 comes out. I don't know, i guess if most people say that its still a good idea I would probably go for it.
