Ok, thank you for the feedback !
I guess it won't change that you see artifacts, until they start filming material in 60fps.
Sadly, there is no hardware or software that can predict movement.
That's probably the reason, why it's not possible to play a 24fps movie in 60fps, without seeing some flaws here and there.
Maybe one day, they'll find a way to tell the hardware or software, in what direction things will move, while there is no frame for it.
So that they don't have to film in 60fps, but give your TV the information for flawless motion interpolation.
Instead of simulating the movement and take a guess how it moves, the player could get this information from a file.
I could imagine it takes less disk space than 60fps material.
How's that for SVP 5 ? You put a blu-ray in your drive, SVP 5 reads the data from it and will save a file on your computer which contains all movement. So the next time, when you play the movie, there's no need for simulating anything - SVP 5 will know how things move from the file and give us flawless fluid playback.
You gotta have a dream !
Or when CD and Blu-ray reach their capacity, maybe we will buy movies on USB-Sticks - they already sell 1TB sticks.
They could film in 60fps if there is enough space to save all material...
