As I far as I understand it the features work like this... But remember, Sony has been tight lipped about it and has given conflicting information so it may not be 100% right. This is just what I assume based on my observations:

Motion Enhancer = Artificially interpolates between frames, thereby creating new frames that were not in the original signal, in order to make motion look more fluid. Standard creates less new frames, High creates more new frames/interpolates more.

Cinemotion = Attempts to detect film material and process it to regain original cadence so it can be displayed at 24fps without judder; Auto1 works together with Motion Enhancer, Auto2 disables Motion Enhancer for film-based material. This should work with both 1080i60 and 1080p30 input; it is not needed with 1080p24 input.

Some people are confused because they still see stutter with Cinemotion Auto2 + motion enhancer disabled when watching movies. IMO that is simply the nature of film which runs at 24fps where we can detect stutter; the type of filming can also exacerbate this. You aren't going to completely eliminate stutter from film without using something like Motion Enhancer; however, you can get rid of the unnatural 3:2 judder without using Motion Enhancer.

So basically I believe that if you want the original frames of your source preserved, you'd go with Cinemotion Auto2/Motion Enhancer Disabled; only exception to this is if you are sending native 1080p24 to the TV, in which case you'd turn off both cinemotion and motion enhancer.

If you want your films to be 24fps but you'd like to see your 30fps content (concerts, nature documentaries, games) made more fluid than original, you'd go with Cinemotion Auto2/Motion Enhancer Standard.

If you want everything to look more fluid, Cinemotion Auto1, Motion Enhancer Standard.
We're all in it together.
