Need suggestions with getting rid of horizontal bands on a TV capture

[Zetto]

Hey guys, I have a question for the local gurus. I have one channel that gets captured with consistent audio and video noise. I do use denoisers like Degrain and fft3dgpu but it doesn't help much. Could someone give me a hint on how to deal with these horizontals bands or bars of noise in the clip I've attached? It has been processed with the following script:

LoadPlugin("C:\apps\multimedia\dgindex\DGDecode.dll")
import("C:\apps\multimedia\AviSynth 2.5\plugins\LimitedSharpenFaster.avs")
video=MPEG2Source("clip.d2v")
audio=MPASource("clip T01 DELAY 65ms.mpa", normalize = false)
AudioDub(video,audio)
AssumeTFF()
Telecide(guide=1,post=2,vthresh=29)
Decimate()
a=last
b=a.RemoveGrain()
fft3dGPU(sigma=5,bt=3,mode=1,sharpen=1)
LimitedSharpenFaster()
crop(12,2,-4,0)
Lanczos4Resize(640,480)

I'm also attaching clip w/o any processing, just straight conversion from mpg to xvid avi

Maybe you can try DeFreq plugin by Fizick but I don't know if it will be efficient on your clip. I've also noticed chroma shifting... look at Turk's T-Shirt.

Your source is really ugly !

yes, Defreq(fx=0,fy=10,sharp=5) can help a bit
