AVS Previewing

[trance]

I"m having trouble getting .avs to preview correctly. The problem is that in all the previews (w/ different settings/filters), they all look the same. In fact, the previews look exactly like the source DVD in WMP and in VDM, although the input and output look different, they don't change (filter doesn't affect the video). I've been at this for a few days now and any help would be great.

Example of a script:

# PLUGINS
SetWorkingDir("D:\PROGRA~1\DVD\GORDIA~1\")
LoadPlugin("mpeg2dec3.dll")
LoadPlugin("Convolution3d.dll")
LoadPlugin("unfilter.dll")
# SOURCE
mpeg2source("E:\DVD\Band of Brothers\Projects\Band of Brothers Disc1 Episode 2\Brothers.d2v")
# CROPPING
crop(0,0,720,480)
unfilter(-30,-30)
# RESIZING
LanczosResize(640,352)
Convolution3d("moviehq")

Maybe I'm getting ahead of myself. When I do previewing a .d2v, i'm really viewing what filters/settings would affect the source (ie if the source has low quality video)? But if the source has high quality video then its pointless.

I think what I'm really looking for is to preview a movie already encoded (that had no previous filters) with new filters? This way I can re-encode with the filters that improve image quality.

Correct me if I'm wrong. Thanks.
