I cant get my Virtualdub mod 1.5.4.1 to work at full speed..it only uses the 66-72% of my cpu..wtf?

What i do:
I use Gordian Knot 0.28 beta and i use dvddecrypter.then dvd2avi and then i set the parameters for vdub mod to do a compressibility check.Thats where gordianknot always want me to point out where vdub mod is,even though i set it the previous time! Anyway,thats not the real problem.When im doing comp check and when im encoding afterwards,i can't get vdub to work more than 66-72% of cpu usage.I run only vdub and the basics in the background (inc. gknot) and vdubs priority is always set to low.
I change it to normal and above normal but nothing changes!!Still 66-72% usage.
Vdub mod is using 200-260 of ram,and a pagefile of 400-450mb.
My current rig is:
P4 2.6 800fsb,on an ASUS p4p800 mobo,with 1024 mb drr ram(2x 512dual)@400mhz,on a maxtor sata 120gb.Windows XP sp1 with all the updates,Divx 5.0.5 pro.

My settings are: GMC,qpel,bidirectional enc.,Lanczos.
i get 10-16fps with those settings,but i think it should be going a lot better,with a 2.6 cpu!!
I found my 1600+ to work maybe faster and maybe better using divx5.0.2,maybe it was because i had no qpel and i was using bilinear,so the codec was bluring things and it looked smoother and cooler.

Plz help me,i cant explain this.why doesnt vdub mod use all of my cpu??

Firstly id update to the latest GKNOT package ie .28.5.2

secondly QPEL is not reccomended (my opinion)

hope the first one solves your prob

Do you think it has nothing to do with hyperthreading?
