Xbox One TV and Cable box options... Which to get?

XBox One features driving choices

There are two things with the new XboxOne that I am trying to decide how to handle wiht new products: The cable box HDMI Pass-through, and the instant-on features.

HDMI Pass-Through:

My main concern here is if my Tivo Premier will work with the HDMI pass through and to what level the HDMI-CEC will interact with it. i spent a while looking for which version of the HDMI is on the TIVO Premiers, but could not find it anywhere (nicluding their site). I really think this is pivotal to me deciding on a set top box. I have heard of other boxes supporting CEC and may just rent one or potentially buy one from a provider if it does and just use it without the great TIVO UI since I would then be using the XBox to change channels and whatnot. Seems not worth $13 a month for the UI. I would like to see a lot of this stuff detailed out my Xbox as well. I suppose this will have a lot to do with those set top box manufacturers as well. What I really want is a Xbox Cable box with full DVR support that works seamlessly with the XboxOne that can input a cable card or whatnot.

Instant-On

This one actually seems a little easier. What Tv's out there turn on the quickest and have a great picture and >120MHZ and 1080p? Since I was planning on getting a new TV anyways, it makes sense to ask this question unrelated to the new XboxOne, but I also am trying to find a TV that matches the quickness of the XboxOne (as shown int he demonstrations, etc...). When I say "Xbox On", I want that TV to start up just the same and just as quickly. Not wait 10 seconds. Any recommendations on manufacturers where this is a non-isssue and it happens almost instantly? I have experience with my Toshiba dn a samsung and shars and whatnot and they all are delayed to some extent. I am assuming I can just ensure the HDMI input for a new TV matches the HDMI1.4 and would be fine with the XboxOne interactions, but are there any specifics about certain Tv's not supporting HDMI-1.4 display input settings. Any idea if that will be supported by any manufacturers?

Performance

This post is all about performance of the cable box and the TV with the Xbox One. I like Tivo and its UI, but I also like the idea of easily switching between gaming, movies and TV. I am a consumer (and an americun) so I want everything fast and very little button pushing. Any other ideas?
