Cinefrom NEOScene footage stuttery in Vegas 8

I noticed that when I have been doing tests using transcoded HDV files shot from my Sony FX1's in Sony Vegas 8, that the HDV m2t files seem to play smoother on my timeline than the new NeoScene AVI file. This is at the "Best" Preview setting with no effects on the clips. I can play the footage smoothly at the "Preview" setting.

But was curious as to why the HDV footage would be much smoother.

I am editing on a dual boot, 2.66 QUAD Core MacPro via Bootcamp and WIN XP. teh footage was tested on a separate internal 7200 rpm Hitachi and external 7200 rpm MAXTOR (via ESATA) drives.

I encoded them with several tests, ranging form the normal "Match Aspect" method to "Deinterlace" and "24P".

When I used the "Match Aspect" method I placed the footage on a HDV 1440 x 1080 with all settings as it.

For Deinterlace, I used the HDV template, but changed the pulldown to "None Progressive"

For the "24P" method I used the 24P 1440 x 1080 preset as is.

Overall the 24P seemed to play the smoothest, with about the same sluggish (slightly stuttery) results using the standard HDV and tweaked Progressive settings.

Of course preview was best using the "Preview" setting on Vegas, but I thought that the "Best" preview would be much smoother, especially since no effects were applied to any clips. I especially thought that the footage would be smoother than the pure HDV footage. The footage was tested on both an independent Hitachi 7200 rpm internal drive and 7200 MAXTOR drive via ESATA card.

Any thoughts from the crew?
