Some deblocking filters do not work

[Selur]

Avisynth 64
Not working Deblock_QED. The preview window does not open.

Works fine here, seems like an issue with the source.

Avisynth 32
Not working Deblock_QED. The preview window opens, but does not see the difference between the right and left windows
Not working AMDCT. The preview window opens, but does not see the difference between the right and left windows

Works fine here.
Depending on the the source the default values might simply not showing much of a difference.
For amDCT set Smoothing->Quant to 31 that should show a difference.
For Deblock_QED using Deblock_QED(quant1=40,quant2=40,uv=1) should also be visible, but QED is meant for light deblocking so depending on the source differences might not be that easy to spot.
