There is no function named unfilter
 

After spending 3 hours fixing the "the resolution of the video is illegal unfilter" error, I encountered this. I would normally go on, but I'm exhausted now. =_=

I followed this black prince's Guide. ToK created these:
- video.avs
- Video.m1v
- video.tpr
- VideoTest.m1v

But, when I played Video/VideoTest, the whole video was a clip displaying: "There is no function named unfilter."

This is my script:

unfilter(50,50)
GripCrop(512,288)
GripSize(resizer="BicubicResize")
STMedianFilter(8, 32, 0, 0, 8, 32)
# SpaceDust() # Optional - for some "not so clean" DVDs.
temporalsmoother(1,2)
mergechroma(blur(1.50))
mergeluma(blur(0.2))
# Convolution3d or DCTFilter for extreme worse cases.
GripBorders()

Any help is appreciated. Thanks in advance. x_X
