MVtools/MVtools 2 frame doubling problem

[Gnodab03]

I just built a new 3.1ghz quad core, and am having some problems getting the MVtools frame doubling to work. It worked in my dual core 2.2 ghz laptop, so I can't quite figure out what's going wrong. the video file I'm trying to use with it (as of this moment, anyways) is only 480P widescreen

using this from the website:

source = last super = MSuper(pel=1,hpad=0,vpad=0,chroma=false) backward_vec = MAnalyse(super, blksize=32, isb = true, chroma=false, searchparam=1,search=0) forward_vec = MAnalyse(super, blksize=32, isb = false, chroma=false, searchparam=1,search=0) MFlowFps(super, backward_vec, forward_vec, num=2*FramerateNumerator(last), \ den=FramerateDenominator(last), mask=0)I get no video at all (the audio still works), and MPC freezes if I try to use the seek bar.

If I use this:

source = last
backward_vec = source.MVAnalyse(isb = true, truemotion=true, pel=2, idx=1, divide=2)
forward_vec = source.MVAnalyse(isb = false, truemotion=true, pel=2, idx=1, divide=2)
source.MVFlowFps(backward_vec,forward_vec,num=4800 0,den=1001,idx=1)

I get 1 or two frames a second at most.

https://forum.videohelp.com/threads/314817-MVTools-AVISynth-script-question-with-FFDShow is a similar thread I had when I was using my laptop before it died.

can anyone tell me what's going on with this? it worked fine in my laptop, and my new computer is easily four times as powerful as my previous one was.

edit: using avisynth 2.5

ATI 3.1 GHZ quad core
8 gigs of ram
windows 64 bit
1 GB Raedon HD 5770

I assume you are using the script within ffdshow.
Do you have the necessary buffering enabled in the avisynth section of ffdshow's configuration settings?
