Help for blocking / artifacts

[moivre]

hello there!
I have a very bad dvd source, with some akwared artifacts, or blocks, I'm not sure.
Here's a pic: (enlighted a bit)

and a video sample: (m2v, 16mb):

I've tried all the denoising from MeGUI, I've tried Deblock from Manao & Fizick, and some wierd script with MVTools, found here in the forums. Nothing helped.
The source is a duallayer DVD, around 8.5mbps PAL, just don't understand how could it look so bad.

If anyone may help me make it cleaner, I'd be delighted!

You may want to try vaguedenoiser. I had pretty good results with a vaguedenoiser + fft3dfilter combo on your video.

Thanks for your try!
Do you want to post the script, too?

These are just starting points and will probably need to be tweaked to fit the source better.

For the artifacts in the picture provided:
vaguedenoiser(threshold=2, method=3, nsteps=8)
fft3Dfilter(sigma=1) //that's right, spatio-temporal filtering on a single frame

and for the video sample:
hqdn3d(ls=1.5, cs=1.0)

I'm not sure if you're going to be using segmented filtering or just applying the filters to the entire video, so you may need to combine and adjust the filters a bit.
