There is a lot of confusion about what "real cinema" and "true motion" do. Honestly I'm confused little bit myself, so I'll try to explain what I know and what I'm confused about. RC=real cinema, TM=true motion
1. RC - off, TM - off
TV displays signal as is, I'm not sure if it's at 60Hz or 120Hz, but I think it is 60Hz and 24FPS movies use 3:2 pull up
2. RC-on, TM-off
24 FPS source is displayed at 48Hz with 2:2 pull up. This is pretty much how you watch movies at the theater.
I'm not sure if 24 FPS recorded movie and transmitted to tv at 60Hz let's say from cable, is converted back to original 24FPS and then displayed at 48Hz, I don't think it is. And I'm still not sure what happens to 60FPS video source, I think it's displayed at 120Hz?
3. RC-on, TM on
24FPS movies are displayed at 120Hz with 5:5 pullup, with interpolation (de-judder, de-blur), still not sure what happens with 24fps movies broadcasted at 60Hz.
4. RC-off, TM-on
Again, not sure if TV uses 60Hz or 120Hz. 24FPS source will be pulled up 3:2 and interpolated if 60Hz used.
So my still unanswered questions are: Does TV use 60Hz for display at all or just 48Hz and 120Hz?
May not be that important, if it uses 120Hz at all times, it probably just blinks each 60 Hz frame twice, except for 5:5 pull up with 24FPS source.
Another thing I wonder is what happens to 24FPS movie broadcasted to TV at 60Hz with 3:2 pullup already.
Is this ever reversed and reassembled into original 24FPS or not?
If it's not, then it would be critical to get DVD/Blue Ray capable of outputting 24FPS and set it to do so. Otherwise the capabilities of Tv to display 48Hz and 120Hz are totally wasted and some judder form 24 FPS recordings always present.
