I'm here because I want a Tablo, and almost bought one, but just realized by accident that it doens't have this very core feature--and I'm preaching to the community that it is indeed a core feature, and needs to be added and not ignored.
My guess is, you've never had this feature. That's why you don't understand it.
I didn't realize that this community was here to make people gather and feel better about themselves because they all have the same (faulty) thing and experience. Oh, wait--it's not.
Why are you so upset about a dissenting opinion? Do you honestly believe that Tablo should never be criticized or encouraged to do better, especially on such core functionality as this? Again, imagine a car company creating a family sedan without doors. Would you be there defending them simply because you bought one, despite the fact that "doors" is a feature every family sedan has had forever?
If I am somehow forcing you to see the reality that Tablo isn't all unicorn breath and rainbows, and you don't like that..well, I don't know what to tell you. Tablo isn't perfect, and is in fact lacking a very core, very fundamental DVR function. I'd like to buy a Tablo for all that it is otherwise, but none of that overcomes its lack of core functionality.
