I have 40" Samsung LE40f86 TV connected to PC.
No matter how I try I can't achieve smooth 23.976 H.264 playback unless I write an AVS script with AssumeFPS(60).
Of course there is no point to watch movie at double speed without a sync.
All other options like setting refresh to 24, 25, 30, 50 or 60, writing a script with ChangeFPS command to any of theese rates nor enabling 100MHz motion plus on TV does not produce smooth playback.
Is it full stop? Is not there a cure?
PAL DVDs play smootly. They somehow translate to 60Hz refresh without an ich?
The CPU horspower is not a problem. It is almost idle when I watch full HD H.264.
Can somebody write a few lines of AVS script for me or suggest anything?

P.S. I wrote an avs script to interlace video from 23.976 to 59.94, but it makes matters worse:

Video = DirectShowSource("hns-skyf.mkv")
Video = SeparateFields(Video)
Odd = SelectEvery(Video, 8, 0, 0, 2, 2, 2, 4, 4, 6, 6, 6)
Even = SelectEvery(Video, 8, 1, 1, 3, 3, 3, 5, 5, 7, 7, 7)
Odd = Trim(Odd, 1, 0)
Video = Interleave(Odd, Even)
Video = AssumeFieldBased(Video)
Video = Weave(Video)
Video = AssumeFPS(Video, 60000, 1001)
Return Video

In fast moving scens like plane landing the background moves in noticable steps. Is it meant to be?

Are there HD TVs which play 23.976 well?
