I have a mpeg2 file which is pretty bad condition. I assume it has blocking artifacts all over the video. How can I determinate this problem ? Help would be nice.

I don't see any block noise. I do see field-blending, which must have been some moron's idea of deinterlacing. I assume you see the bad flicker. Also, bad video levels and crushed blacks. Thought I'd give it a try. Not much you can do about the blending, though. Maybe someone will have some ideas.
Code:MPEG2Source("VTS_01_2.demuxed.d2v") ColorYUV(off_y=8) ReduceFlicker(strength=3,aggressive=true,grey=false,planar=true) ReduceFlicker(strength=3,aggressive=true,grey=false,planar=true) LSFMOD(edgemode=2) ConvertToRGB32(matrix="Rec601",interlaced=true) LoadVirtualDubPlugin("D:\VirtualDub\plugins\Deflick.vdf", "DeFlick",1) DeFlick(0, 10, 0, 0, 0) ConvertToYV12(interlaced=true) return last

Deflicker didn't work. Script error is : invalid arguments to function "deflick" . Help would be nice.

Are you using the same script?
You must have deflick.vdf in your VirtualDub plugins.
There are 5 (and only 5) parameters to the VDub filter. Four of them are 0's, one of them is 10. Seems kinda tough to get that wrong. Check for typos.- My sister Ann's brother -
Yes I'm using same script.
My VirtualDub is portable. Plugins works when I open with VirtualDub directly but no luck with Avisynth.
There is no Avisynth filter for this? -
Sorry to see you have to use an unconventional setup. That's gets you out of Virtualdub usage unless you want to save Avisynth output and open it separately in Virtualdub, because there's a lot of Virtualdub stuff that's very handy, especially for color work.
DeFlicker.vdf is a weaker version of ReduceFlicker. It was just enough to clear the very last of the flicker. You can try another iteration of ReduceFlicker that's less aggressive to see if it clears the image, but it will further soften the video slightly more than DeFlicker does.
Code:ReduceFlicker(strength=3,aggressive=true,grey=false,planar=true) ReduceFlicker(strength=3,aggressive=true,grey=false,planar=true) ReduceFlicker(strength=2,grey=false,planar=true)

I don't think you need to use deflick. In fact, a single call to ReduceFlicker() is probably good enough for most of the clip. Even that is damaging the picture quite at lot. I'd look at a little noise reduction though. Maybe RemoveDirtMC(30) or so (after flicker reduction).
