Flicker in MPEG Vegas 6 renders

I can't figure out what I'm doing wrong with rendering this clip (and others on which I've experienced similar poor results).

Watch this 15 second MPEG2 clip (pay attention to the apples, for instance, and use "full screen" to really see it), and notice how it looks like the camera is focus hunting. It looks horrible on the DVD on TV. My first thoughts after watching this were " I should have used manual focus".

But then I went back and watched the miniDV tape directly on the TV, and it was fine. No flickering, peoples faces looked sharp and clear. So it's not the camera, its the MPEG2 rendering quality. (also, the captured AVI file looks fine.)

So (starting with a DVD-Arch template in Vegas 6) I went from my usual selection of 7.5 max/6 avg/2 min and re-rendered using 7.7/7.2/2 AND 2-Pass. But it was no better (this latest render is what the 15 second clip above is at).
The Quality slider is maxed out at 31.

I tried using a .02 motion blur, and separately "reduce interlace flicker". Both cured the flickering, but obviously softened the footage which doesn't look that great either.

I can also post the 57MB AVI clip if need be. The captured AVI looks fine too when played on the computer.

Thanks!!

I think the flicker is caused by the fact I am using slo-mo on this clip in my project: it is CTRL+DRAGGED to a value of 0.913.

Is it normal for slo-mo to cause such an apparent and annoying pulsating flicker?

Slo-mo could cause that. but it looks like it could be that you use pan/crop or track motion & that made the fields off. the background people look pixalated too.

if you could post the original avi then i'm sure someone could try rendering it on their system to see if that helps.
