annoying decimate problem

[subcool]

before anyone even asks, I'v searched the forums and tried stuff for 2 hrs long...
I have a video wich is approx 120 fps (119.8811 to be exact), now decimating it to 23.976 is no problem.
But, as soon as i encode it (or preview) the video plays TOO fast.
I tried tdecimate, fdecimate, smartdecimate, selectevery(5,1), decimate(2).decimate(2).decimate(5) and whatnot...

I really do not understand why its not playing at normal speed >_<
its like the video is being fast forwarded all the time, but the audio isn't...

to make things clear, i wanna go from 119.8811 fps -> 23.976

actually i figured it out -_-;
appears decimating doesnt work well when you use directshowsource() for a .avi
using avisource works better... x_x
