Stuttering after rendering

Hi -

I have a small clip - mayb 10 - 15 seconds long - that I have applied Color correction, Brightness and Contrast, and Film Effects to. I am trying to give the clip a desaturated, high contrast look, with lots of grain. It looks fine, but...

After the render, the output clip stutters, almost as if my PC isn't powerful enough to play it back. I have tried several things to fix this problem - using "Add Noise" instead of "Film Effects", reordering the effects in the chain, etc. The only thing that seems to help is if I use "Add Noise" and turn off animate - which is completely not what I want, as it makes it look like I have dust on my lens instead of noise.

For what it's worth, I have used this same effect on a black and white clip with no problems. This only seems to happen on a color clip.

Any thoughts here? I have attached a rendered clip (1280x720 30p, wmv format) if anyone wants to see the problem...

Oops - I just realized the size limit on WMV is 640x480. Let me find another place to host it. I just tried rendering to 640x480, and wihle I feel it still was not right, it was not nearly as bad as 1280x720.

New bit of info - Quicktime 7 / Sorenson 3 rendered file is larger, but does not have this issue. It also uses more CPU than WMV did, so I don't think I am CPU bound.
