Avisynth, get no video just the audio
 

seems i broke a rule sorry about that her's my problem

ok so this is the scipt im using:
## DLL Section ##
#
LoadPlugin("C:\Filters25\MPEG2Dec3.dll")
LoadPlugin("C:\Filters25\GripFit_YV12.dll")
LoadPlugin("C:\Filters25\STMedianFilter.dll")
LoadPlugin("C:\Filters25\asharp.dll")
LoadPlugin("C:\Filters25\unfilter.dll")
LoadPlugin("C:\Filters25\undot.dll")
#
####

## Defined Variables and Constants ##
#
MaxTreshold = 1.50
nf = 0 # Current frame.
#
####

## Main section and static filters ###
#
AviSource("********.avi")
#
undot()
Limiter()
asharp(1, 4)
GripCrop(352, 288, source_anamorphic=false)
GripSize(resizer="BicubicResize")
STMedianFilter(3, 3, 1, 1 )
MergeChroma(blur(MaxTreshold))
MergeLuma(blur(0.1))
#
#

## Linear Motion Adaptive Filtering ##
#
# ( Portions from AviSynth's manual ) - This will apply temporalsoften to
# very static scenes, and apply variable blur on moving scenes.
# We also assign a variable - and this is why a line break is inserted:

SwitchThreshold = (Width<=352) ? 4 : (Width<=480) ? 3 : 2
ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf >= SwitchThreshold ? \
unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ) : \
TemporalSoften( fmin( round(2/nf), 6), round(1/nf) , round(3/nf) , 1, 1) ")

#
#
#

GripBorders()

Limiter()

#
#
## Functions ###

function fmin( int f1, int f2) {
return ( f1<f2 ) ? f1 : f2
}

#

When i load this into media player i get no video just the audio the same happens when i open it in TOK help would be much appreciated thanks... broke a rule sorry about that.....here is my problem
