    That looks more natural to me since I've been used to seeing it for decades.

    If you don't ever use the TiVo for Amazon, Netflix or YouTube, is there any benefit to switching the output to 1080p vs. 1080i?

    Basically what you're selecting is what you want the Tivo to transmit to the TV. If you want the Tivo to pass-through every program's native resolution and let your TV handle the scaling, select all resolutions on the list (or at least 720p and 1080i). The downside is that some TVs might go blank for a split second as it jumps between resolutions. (channel surfing, entering and exiting menus, etc)

    The Tivo's scaler is actually fine. I can't tell a difference in my case between the Tivo scaling or the TV's scaling (I have a 1080p TV). So just to avoid the resolution blinking, I have it set to 1080p/60.

    If a TV is 720p, I would select either 720p or both 720p and 1080i to avoid unnecessary image re-processing.

    Movies are shot at 24fps so watching them at 1080p/24 means that the least amount of processing has to be applied to the video an you're getting the the truest picture. However 24fps only works on 120Hz or better TVs because 60 is not evenly divisible by 24. With a 120Hz TV they can play a 24fps video by simply displaying each frame for 5 cycles. But with a 60Hz TV they have to use 2:3 which means they alternate every other frame for 2 cycles then 3 cycles. This can create a slight stutter that some people can perceive. Some processors use a special interpolation technique to convert the video instead which can produce a smoother picture, which could explain why it looks better coming from one device then the other.

    And to further complicate things, not all 120hz TVs apply 5:5 pulldown. So some apply 3:2 pulldown to go to 60 Hz then double that to go to120 Hz.

    My TV does this and I have noticed some unusual jumpiness (for lack of a better word) when watching the latest episode of Hell on Wheels. I didn't think that would be broadcast in 1080p but I'd like to understand why that show looks jumpy and most others don't.
