SetEvery vs ChangeFPS

[red5goahead]

Which is the difference of these two avisytnh scripts

SetMemorymax(256)
SelectEvery(6,1,1,1,2,2,3,3,3,4,4,5,5,5,6,6)

and

SetMemorymax(256)
ChangeFPS(60)

I set my plasma to 60 HZ.
If I play an mkv avc1, ac3, 23,976 fps with Media Portal, CoreAvc 1.6.5 and ffdshow for AviSynth postprocessing with
first script it work, My goal is bring fps closed to refresh monitor
with a simple puuldown 2:3. it work and the audio is synched.
with the second script the video lags and the lag raise progressivly.

any suggest?

The first does a strict multiply by 5/2, the second does whatever is needed to output 60.0 fps.

i.e. the 1st will do 23.976 -> 59.94, the second will add an extra frame every 1001 to ensure exactly 60.0 so your cadence will be 3:2:3:2:3:2:... ...3:2:3:3:3:2:...
