2nd Gen VHS placed on DVD

[NoodleMaps]

I received a DVD that was obviously recorded on a set top unit. The image quality is just barely acceptable, I want to try and make it better.

I've tried different version of this script


MPEG2Source("I:\Oingo US Fest 83\Oingo83.d2v")
ConvertToYUY2(interlaced=true)

AssumeBFF()


fft3dfilter(sigma=3,bt=1,interlaced=true)

function MCremovespot (clip c)
{
vfw = c.mvanalyse(pel=1, isb=false, blksize=8)
vbw = c.mvanalyse(pel=1, isb=true, blksize=8)

clensed=interleave(c.mvcompensate(vfw, thSCD1=1000),c,c.mvcompensate(vbw, thSCD1=1000)).clense().selectevery(3,1)
spotmask=yv12lutxy(c,clensed,yexpr="x y - abs 24 > 255 0 ?",Y=3,U=-128,V=-128).expand()
overlay(c,clensed,mask=spotmask)

}
assumetff()

converttoyv12(interlaced=true)
odd=last.separatefields().selectodd().mcremovespot()
even=last.separatefields().selecteven().mcremovespot()
interleave(odd,even).weave()
assumetff()


Deblock_QED(quant1=25,quant2=51)


SeparateFields()
LimitedSharpenFaster( ss_x=1.5, ss_y=1.5,
\ Smode=4, strength=150, radius=2,
\ Lmode=1, wide=true, overshoot=1,
\ soft=36, edgemode=4, special=false,
\ exborder=2 )
AddGrain(10,0,0)
Weave()

colorYUV(cont_u=18,cont_v=12)


But I keep getting an image that looks like a web stream when I watch it on my set.

I'm trying to remove the white drop out noise from the analog source, remove noise and sharpen the image. I would also like to do a little color correcting and levels corrections as well. Just haven't, since this script is giving me troubles.

Any help would be greatly appreciated and insight into what I am doing wrong here.

Here is a 9Meg VOB file cut from the DVD.

Okay I think I spotted one of my problems with the AssumeBFF () then further down the script there is the assumetff ()

Left over from a previous script when it was BFF. So I corrected this. But it's still not looking right.
